Truck drivers face a number of additional drivers on the road that car drivers never have to worry about. Because a semi-trailer truck can weigh up to 40 times more than a passenger car, topping out around 80,000 pounds, it can be much more difficult to control. These large vehicles need approximately twice the distance as passenger cars to safely come to a complete stop. In addition, even a small shift in weight or balance can throw a truck off of its course. One of the greatest risks to a truck's equilibrium is the possibility of a tire blowout.

Tire Blowout Causes

When a tire is poorly manufactured, it may fall apart long before it is expected to. A tire defect can affect a truck's performance and create a high risk for an accident if the tire blows out while the truck is in motion. Some of the common causes of defective tire blowouts include:

  • Tire bead failure
  • Tire tread loss
  • Zipper failure
  • Tire tread separation
  • Sidewall failure
  • Tire belt separation

Any of these defects could lead to a blowout, which may cause the truck driver to lose control of the truck and cause an accident.

Accident Risks

To other motorists, a tire blowout on a truck may not seem like a major concern since a semi-trailer typically has 17 others to spare. However, a tire that suddenly pops or shreds may throw the trailer off balance, causing the truck to fishtail, jackknife, veer off of the road, or possibly even roll over. Other vehicles can get caught up in the accident and unsuspecting drivers could be severely injured or even killed.

If you or someone you love has been injured in a truck accident caused by a tire defect, the truck tire manufacturer may be liable for the defect and you may be entitled to compensation for your injuries and damages ..

Whatever Happened to Cheap Tires?

You have probably noticed it by now. You go to the grocery store, and your bill is way more than you had to budget for a few years back. You leave the store to fill up the car, and notice you have to drop almost $80-100 each time just to fill the tank. You get home and open the mail to find your electric bill is over $200. Prices are going up. Haven’t noticed it yet? Well, then try to go buy some new tires for your car.

The Situation

That’s right. Along with everything else going up in price in the last 10-12 years, tires have followed the trend. According to the U.S. Bureau of Labor Statistics(6), the average price of a tire has climbed from $97.10 in January 2000 to $134.91 in September 2012. That might seem pretty modest. But remember, you’ve got to buy four of those things! Taking that into account, the average consumer is likely to spend over $150 more for a new set of tires than they did a few years back. Why has the price of commercial truck and consumer vehicle tires continued to rise over the years? In a quick lay-person analysis, it can be summed up by three main factors: Tariffs, Trees and Trade.


One of the biggest exporters of cheap, entry-level tires is China. During the darker days of the recent U.S. Economic recession, the Obama administration slapped heavy tariffs on all tire imports from China in an attempt to protect American-based manufacturing jobs. Tariffs, if you didn’t know, are basically taxes that the folks in China have to pay to the U.S. Government to bring their tires into America to sell. According to an article by Tire Review(1) the tariffs started as steep as 35% in September of 2009, and dropped 5% each year until they were supposed to be ended this September. Think of it; that’s $35 extra for every $100 of tire coming in from China! In order for the company in China making the tire to make a profit, and the American-based store selling the tire to make a profit, they are forced to raise the price. Who gets that extra $35? Not you, but the government. Where does that extra $35 come from? It comes out of the potential savings you, the consumer, could have had with a cheaper tire.


An amazing fact about tire production is that a good portion of the rubber used for tire production comes from simple rubber trees grown in Thailand, Indonesia and Malaysia. According to Wikipedia(2), 72% of all rubber in the world comes from these three countries alone. Unrest in these countries can impact rubber prices worldwide (remember the riots and violence in Thailand in recent years?). Flooding, typhoons and heavy rains can also affect production, as it relies on actual people walking out to the trees to ‘tap’ them daily for rubbery latex sap. You wouldn’t want to walk out there in a typhoon. Neither do they.

Nature and politics can affect the delicate process of harvesting rubber for tires in these countries. But another aspect of the process can affect the ability of rubber growers to respond rapidly to increased demands for their product. Rubber relies on natural processes for production via the growth of trees. These trees take up to seven years from planting to even begin production.

So, say you have a dramatic increase in demand for rubber worldwide, such as China beginning to churn out an army of cars for their own domestic use in the last 5-7 years. All of these cars need tires, which need rubber, which need trees, which take seven years to grow before they produce latex… The reality is that a sharp rise in demand for rubber worldwide cannot be matched with a quick increase in rubber production, and herein lies a major factor in rising tire prices.

What about synthetic rubbers you say? Can we still be so reliant on tree rubber for our consumer tires, truck tires and tractor tires in this modern age? Synthetic rubbers are generally produced from by-products of oil. Remember how much it cost to fill up your gas tank in the example above? Relying on synthetics when crude oil is $88.62 a barrel in 2012 compared to $25.40 a barrel in 2002(3) will not help towards cheaper tires.


The world only has a few countries with limited land and trees providing rubber for a rapidly growing tire market across the world. The unavoidable result is competition on the world markets for the limited rubber supply as demand rises, driving up the prices of raw materials for everyone. These fluctuations can be dramatic and sudden. According to an analysis paper by Brett W. Fawley and Luciana Juvenal of the Regional Economist(4), during 2010 the price of rubber increased by 114 percent. The culprit?

“The run-up in the price was largely attributed to bad weather, low stocks and growing demand from China’s automobile industry,” Fawley said.

Consider this for the situation today. The cost of a pound of raw rubber in October 2002 was only $0.37 cents. Today in 2012? Try $1.45 a pound(5). That is almost a 300% increase in 10 years! This rise due to market competition, limited supply and regional weather issues inevitably translates over to a narrower profit margin for American tire companies and a need to continue to raise prices for the consumer.

What Can We Do To Find Cheap Tires?

So what can I do to find cheaper tires, whether they are car tires, truck tire, or tractor tires, you ask? While you can’t go out and grow your own rubber trees, you can do a few things.

First, you can shop around for seasonal or ongoing tire sales and special deals. You can find these for consumer tires or even discount truck tires with some specialty dealers. Sometimes a tire dealer may have too many of a certain tire in stock and need to make room for the newer models, thus motivating them to have a discount tire sale. By being patient and shopping around online and in local stores, you can often find a great deal.

Second, you can limit your tire purchases to online tire sales from web-based stores. These are real tire dealers that usually work with a large national supplier, but sell to you direct from the warehouse without a storefront to fund and manage. Without the cost of having to maintain a traditional brick-and-mortar store, they save money, and you do too!

Third, you can consider buying used consumer tires, used discount tractor tires, or used discount truck tires. While that might sound odd, it is an increasingly popular market for people strapped for cash but needing better tires than what they currently have. Quality of course varies in wear and tear, but sometimes you can find a great deal. Let’s say someone buys a new car but wants a different kind of tire on them. The “old” tires that have only a few miles on them come off and go to the used tire dealer, as good as new but only a fraction of the cost to buy! If you are diligent in searching around, used tires can be a great money saver.

As the cost of everything continues to climb, consumers need to be creative to save money on groceries, gas and, of course, tires. If you have other tips for saving money with tires, please contact the author of this article and your suggestions might be included in future articles.

Proper Semi Truck Maintenance

How To Decide Whether To Go With High Or Low Profile Tires
Check out US Trailer Rental


Every year there are thousands of fatalities involving semi trucks in the Untied States. The destruction that can be caused by a truck is significantly more severe than that of a regular car. Just the size of a truck alone can lead to the serious accidents involving multiple cars at a time. In an effort to keep truck accidents to a minimum, the United States government has a number of requirements that truck drivers and trucking companies must meet. One requirement and integral part of truck safety is frequent truck maintenance checks.

What Maintenance Entails

Maintaining a semi-truck involves a number of procedures. Unlike a regular car – which must be inspected once a year –trucks suffer from constant wear and tear and maintenance checks are an ongoing necessity. Necessary truck maintenance includes:

  • Frequent checks of all fluid levels – a vehicle as large as a 18-wheelers require much larger volumes of fluids and these fluids must remain clean in order for the vehicle to function properly.
  • Brakes checks – the weight of these large vehicles makes the brakes particularly vulnerable to giving out. The amount of damage that can be infected on the highway by a truck without functioning brakes is massive.
  • Tires – the weight carried by all 18 tires can cause frequent blow outs.
  • The engine
  • Lights – trucks have many lights on the vehicle to alert other drivers to their presence and their movements. Each of these lights should be properly working.
  • Turn signals – because trucks are so large it can be very difficult for a truck driver to know if his or her turn signals are out. Therefore they should be checked before leaving for a job.
  • Mirrors – the mirrors on 18-wheelers are the only things allowing the driver to see what is going on to the side or in the rear of him or her.

Proper vehicle maintenance is fairly easy and performing maintenance frequently can save lives.

Timber and Its Use in Commercial Truck Construction

Solving Starter Problems on 1992 - 2006 Ford Products
Check out US Trailer Rental


Many types of timber are used in commercial truck bodywork today, and it is used in a variety of different forms ranging from sections for framing, chipboard for partitions, to faced plywood for decorative panels. Manufactured timber panels are also used in conjunction with other materials such as aluminum and plastics to produce panels for special purposes which include heat and sound insulation and to improve resistance to general wear and the weather.

Some timbers are more suitable for vehicle bodywork than others because of their superior strength, resistance to wear, decay and fire, or appearance.

Although timber is used in many forms, it is all obtained from either soft wood trees or temperate or tropical hardwoods.


There are a large number of softwood trees, which include many varieties of pine, fur, and spruce which make up about 90 per cent of all timbers used generally in the U.S.A and Europe. These trees are normally found in the northern hemisphere; most of them are cone bearing and evergreen, but there are some exceptions. In fact some types of softwoods are harder than hardwoods.

There is a good supply of softwoods and since less time is required to mature and they are easier to work they are generally cheaper than hardwoods. Softwoods are uses for the sides and floors of mineral carrying vehicles, since it is cheaper and easier to replace. It is also used for manufactured panels for other commercial vehicle bodies.


These are obtained from broad leaf trees, and there are over 2000 varieties including such well known types as oak, ash, teak and mahogany. All basal wood, which is much softer than softwoods, is in fact a hardwood, since it is the structure that decides the group not the texture.

Because the hardwoods take much longer to mature, are more difficult to obtain and work, and take much longer to season they are considerably more expensive. However, they are generally much stronger, more durable and have far more uses than softwoods.

Hardwoods are divided into two groups:-

1. Tropical. These are from trees found in Central Africa, India and South America and include the many different types of teak, mahogany and ebony.

2. Temperate. The varieties found in this group are oak, walnut, and ash are some of the temperate hardwoods found in U.S.A, Europe, Japan and Australia.

Hardwoods are used for framing and in some forms of veneer on panels for interior finishing. Also hardwoods such as ash are very suitable for curved framing members.

Manufactured Panels.

Plywood, block-board, chipboard, MDF and hardboard panels are often used instead of solid timber panels, and have many advantages. They can be obtained in larger sizes, are often stronger and are more stable, which means labor costs can be reduced when compared with other methods of covering large areas with equivalent tongue and groove jointed timber.


Plywood is made by gluing layers of veneer together at right angles to each other. This prevents splitting and greatly increases the strength of the panel. Curved members can also be produced by laying the veneers on a suitable mold or form before gluing.

Birch, ash, pine and fir are used in the manufacture of plywood but many other varieties are used for the face side of decorative panels. Plywood is obtainable in several thicknesses and sizes from which vehicle body floors can be made in one piece.

Block board.

There are a number of manufactured boards making use of solid timber core stock. One of these is block board and this consists of softwood glued together and faced with veneers of timber such as birch and mahogany. Large panels up to about 2 inches in thickness are produced and used in flooring and partitions.


Chipboard is made from graded wood chips which are bonded together under pressure with synthetic resins and adhesives to form large strong panels 0.5 inch to 1 inch thick. These can be faced with many different materials to give painted, plastic or veneered surfaces. It has replaced solid timber for many purposes and because of the sizes manufactured it is a useful vehicle building material.

Medium Density Fiberboard (MDF).

MDF is manufactured by bonding wooden fibers together using glue, heat and pressure. It is a very adaptable material, but can only be used for interior bodywork. It must be sealed / painted as it gradually emits urea formaldehyde which is a known carcinogen and eye, throat and lung irritant. Proper safety procedures should always be used when working with this material in any way.


This is another useful material which, because of its smaller thicknesses is very suitable for interior paneling. It is made from compressed timber fibers and usually has a smooth side with the reverse side having a rough or mesh finish.

Identification of timbers.

Since many types of timber are used in vehicle body work, it is possible to identify the more common ones such as oak and teak. Most types have distinct features and properties, and when samples are carefully examined it is often possible to identify a particular type. The following features should be considered:-

1. The general appearance.

  • i) Color – red, brown, yellow, white.
  • ii) Grain – close or open, straight or twisted.
  • iii) Texture – hard or soft, rough or smooth.
  • iv) Figure – shape of grain

2. Weight.

Weighing a sample is not a reliable test since the weight will depend on the moisture content and even the weights of samples may vary.

3. Use a hand lens.

Examination of the surface and end grain may reveal distinctive features.

4. Use a microscope.

The use of a microscope will enable a much closer examination of a thin section.

5. Dissolving a sample.

This will allow a microscopic examination of the shape and size of cells and fibers.

It should be remembered that features and color may be affected by the origin, rate of growth, and treatment since felling and many other factors.

Timber Defects.

One of the main disadvantages with timber is that defects may be present or may develop later. Some of these can be treated satisfactorily but others may require the component to be replaced. Some defects can be avoided completely by careful felling, conversion and seasoning, but a knowledge of the defects will enable you to make the best possible use of the timber that may be somewhat inferior.


These are not always a serious defect since in many cases timber is covered with paint, panels or other disguises and in timbers such as knotty pine they are treated so as to improve the appearance. On the other hand knots should not be present in framing timbers, some decorative panels or other situations where strength or appearance may be affected. Knots are nearly always present and timber is often graded by the distribution and number of knots present. Some timbers have more than others, so careful selection is usually worthwhile.

Splits and shakes.

Shakes appear in various forms and are not always apparent until the tree is felled and sawn into logs. Heart and cup shakes may not present much of a problem but other types such as the ring and star shakes can result in valuable timber being unusable. During the drying out or seasoning the moisture leaves the timber more quickly from the ends than the sides. If this is too rapid other splits may occur.


Many types of timber are affected by various insects, and chemical treatment may be effective. The alternative is to remove and burn the infected part and fit a new piece.

Dry rot.

Timber, which is stored in conditions which are damp or lack ventilation will lose its strength and become soft and spongy. If this happens timbers should be destroyed.


This is a common defect and is caused by uneven shrinkage during seasoning. Softwoods are more prone to this, since softwoods contain more moisture than hardwoods. Warping can be reduced by sawing the logs radially instead of tangently. If you examine the end grain of planks it is possible to decide which way they have been cut from the log.

Causes of timber defects.

  • i) Storm damage.
  • ii) Exposed growing conditions.
  • iii) Inexperienced felling.
  • iv) Incorrect conversion.
  • v) Poor seasoning.
  • vi) Bad storage conditions.
  • vii) Careless selection and use.

Seasoning timbers.

Living trees may have a moisture content of between 50% and 100% and since this is too high the trees, when felled have to be seasoned or dried until the moisture content is reduced. Timber for vehicle body work should have a moisture content of 12 %- 15%. If the moisture content is too high the timber will dry out further and shrink after use. If it is too low the timber will absorb moisture from the atmosphere and possibly swell. To find the moisture content a sample of timber is weighed in its normal condition and then weighed again after it has been carefully dried out. The moisture content is then calculated as follows:-

The moisture Content of the timber (M.C. %) is calculated by taking the wet weight, subtracting the dry weight, and dividing the answer by the dry weight and multiplying by one hundred.

The method of drying out a piece of timber to obtain its moisture content is unnecessary in practice, because electrical instruments are used to give instant readings There are a number of reasons why timber should be properly treated (seasoned):-

  • I) It is much stronger than unseasoned timber.
  • II) There is less risk of decay and attack by insects.
  • III) Painting, staining and other finishing processes can be carried out successfully on seasoned timber.

We should remember that the cells in a piece of timber are like wooden buckets. Large amounts of water in the cavities and the walls, so it is essential for timber to be properly seasoned. After the trees have been felled, the logs are taken to the saw mill where they are converted or sawn into planks or other sections. Since this exposes a greater surface area to the atmosphere seasoning time is reduced. The method used to saw or convert the logs will also affect the shrinkage, warping or other timber defects discussed previously.

Air Drying.

The sawn timber is piled in stacks with sticks or wooden strips separating each layer. This allows the air to circulate freely around each piece. The top of the stack should be protected from the sun and the rain, and since moisture will dry out more quickly from the ends of the planks, these are sometimes protected to prevent end splits. The air drying method is cheap and often leads to better quality timber, but it is a slow method, taking up to several years. The timber is liable to staining and insect attack and the moisture content is very rarely less than the surrounding area.

Kiln Drying.

This is a much quicker method, which results in timber with a more closely controlled moisture content. The timber is placed on trolleys and put in a kiln where the temperature and humidity are controlled. Air circulation may be by natural draft or forced by electric fans. Artificially seasoned timbers may be more brittle and other defects may occur, but the reduced time required is big advantage. Some timbers are air dried for a period before being kiln dried.

Timber Storage.

Seasoning timber processes may take several years and the timber may be stored for a further period before it is used. In order to keep it in good condition certain precautions must be observed:-

  • i) To prevent staining the timber should be protected from chemicals and other foreign matter, e.g. soot.
  • ii) Excessive rain and heat should be avoided and if stored indoors sufficient ventilation should be provided.
  • iii) It should be stacked in a proper manner to prevent boards becoming twisted or warped. The supporting blocks should be directly under each other otherwise the timber will begin to bend.

Wood preservatives suitable for use prior to painting.

This type of preservative is usually of a low viscosity and can normally be used prior to the application of coach or decorative enamels and their painting process. It can be applied by brush, spray or dipping and is normally allowed overnight to dry before application of the above mentioned paint systems. This promotes good adhesion and helps to reduce the problems of timber disease and rot.

Before using this type of product it is essential to make sure that it does not contain any waxes or silicone additives.

Priming of timbers.

Before the priming of any timber it is important to check that the timber is clean, dry and free from any oil residues. The timber should be thoroughly flatted with a suitable grade of glass paper and degreased with a ‘lint-free’ cloth which has been dampened with white spirits or a suitable solvent.

Priming should then be carried out using a suitable primer. It is essential when priming that all areas are adequately primed. This includes timber ends and tongue and grooves, where areas are to be covered with metal fitments or body sections. The reason for this is to prevent the ingress of moisture which would result in paint flaking.

Timbers containing knots should be treated in the following manner, prior to priming:-

I) The knots should be burnt with a blowtorch to extract surplus resin.

II) The timber should be thoroughly rubbed down and degreased as above.

III) Each knot should be treated with one or two coats of shellac, and allowed sufficient time to dry.

IV) Prime the timber as above.

Wood finishes.

These are non-pigmented finishes. Among those available are wax polishes, sealer coats, long and short oil varnishes, alkyd varnishes, yacht varnishes, single pack polyurethanes and teak oil. All these are suitable for brush application. For spray application only, use the following – cellulose lacquers, two pack polyurethanes, two pack catalyzed lacquers and single and two pack epoxies. The requirements of a wood finish are:-

  • i) Color flexibility.
  • ii) Build.
  • iii) Life expectancies.
  • iv) Acid or alkali resistance.

Sealers and wax polishes.

Sealers – These are cellulose based.

Waxes – These are petroleum based. One example is chilled wax which is fairly quick drying, gives little discoloration to the wood, and produces a good average finish.

Waxes – Silicone based. These waxes are very quick drying and produce a hard waterproof finish. The wood needs to be sealed before use, and it tends to give it a cloudy appearance.

Waxes – Beeswax. This is a natural product from honeycomb which has been rendered down with white spirits. It can be applied by brush or rag and produces a good finish that can be re-polished.

Long oil varnishes.

These contain more oil than resin in its formulation. The resin used is usually an alkyd or fossil resin. Long oil varnishes are flexible, due to the amount of oil and have good durability, making it ideal for exterior usage. It also has a fairly clear finish. Polyurethanes are used for wood which is left in exposed conditions, but tends to be rather soft for interior use. The life expectancy is two to two and a half years, and a four coat system is recommended, i.e. apply one very thin (diluted) coat followed by three full coats.

Short oil Varnishes.

These varnishes are quick drying but tend to be rather brittle. They dry to a hard finish and are more suitable for interior use, as they do not have the flexibility for exterior use.

Alkyd varnishes.

These are clear quick drying varnishes which are suitable for indoor and outdoor use. They are popular as a varnish for vehicle bodies, and are also applied as a four-coat system.

Teak oil.

This oil is easy to apply, but liberal coatings are required to restore the natural color of the timber.

French polishing.

This is based on shellac and methylated spirits. It is quick drying and causes the timber to darken. It is applied using a pad, made of a packed piece of wool or gauze, covered by a piece of cotton cloth. It is however, brittle and easily damaged by water and white spirits. It is mainly used in antique furniture.

Nitrocellulose lacquers.

These lacquers come in two types, the pre-catalyzed and the nitro-urethanes. These contain amino and polyurethane resins respectively.


There is no doubt of the advantages of using timber in commercial truck bodywork today. Certainly other materials have and will come along to try and replace it, but for its versatility and availability it is still unrivalled and will be for a long time to come.

Knowing your timbers and how to look after them will ensure the maximum life expectancy from your truck or commercial vehicle.

Tires For Trucks

Recreational Vehicle Trailer Tire Maintenance

The truck tire, undoably, is one of the main components of the truck, which influence on all its factors, such as a fuel consumption, steerability, resilience, brake properties, comfort, durability, etc. The design of the tire, description of an identical simplicity, is complex enough. The tire consists of more than two hundred different elements, using the best quality materials. In this article we tell about tires for trucks and buses. The information is oriented on direct users of tires, who are engaged in trucks operation.

The pneumatic tire for trucks represents the elastic envelope meant for setting on a wheel rim and filled by air under pressure. Against the way of sealing the pneumatic tires may be tubed or tubeless. The tubed tire consists of a tire casing and the tire tube with the inner tube valve. The tubed tires for trucks are assembled on rim strips and flat knockdown rims. The design of rim strips and tubes should correspond to a design of tires. The rim strip is made in the form of a shaped rubber gasket and sets between the bead of tire, the tube and the wheel rim. It protects the tube from a jamming between the bead of a tire and a rim and from damage by unevenness of a rim. The tire tube is a circular rubber tube with the special valve, filled by air.

The tubeless tire for trucks represents the advanced tire casing which simultaneously performs the functions of the usual tire casing and the tube. The air chamber in the tubeless tire is formed by a tire casing and a wheel rim. The elastic rubber-cord casing of the pneumatic tire also represents a tire casing in the tubeless tire. It receives tractive and brake efforts and provides the road adherence. The basic elements of a tire are a carcass, a breaker, tread, valance and beads.

The carcass tire for truck is a rubber-cord casing basis (a power part) of a tire. It is made from one or several coats of the rubberized cord with the rubber interlayer, fixed on the bead rings. The breaker consistants of one and more coats of the rarefied rubberized cord, divided by rubber interlayer, and it is located between a carcass and a tread. Depending on a material of a cord in the breaker the tires are subdivided into the tires with textile breaker and metal-cord tires. And if both the carcass and the breaker are made of metal-cord, the tire named all-steel-tire.

Van Tires – Tips For Choosing the Best Tires

Timber and Its Use in Commercial Truck Construction
Check out US Trailer Rental


Van tires often face challenges that are a combination of light truck duty and passenger car duty. That makes it a little bit of a puzzle when it comes to choosing tires. Now likely your tire dealer will steer you in the right direction, but here are 4 tips to consider when choosing van tires.

Minivans As Cars Or Trucks

Certainly many minivans fit right with passenger cars when it comes to choosing tires. That’s so because of the weight of the vehicles and the loads they will be expected to carry. But that may not always be so. Some minivans are indeed used more like trucks and the loads carried should be considered when picking a tire.

Consider too that even some minivans are built n truck frames and ride and carry cargo like small to mid-size trucks.

Heavier Vans

Full size vans certainly take on the character of pickup trucks. Most full size vans are in the weight range and the load carrying capacity of full size pickups. That often suggests a light truck tire would be best for a bigger van. Some larger vans may even need more than a light truck tire.

Lightly loaded large vans may still work well wit passenger car tires, but often loads on these vans are marginal with passenger car tires.

Trade-Offs With Truck Tires

The switch from passenger car tires to light truck tires often happens because of load carrying capacity. The trade-off to get more load capacity is often ride quality and noise.

The light truck tires sport a heavier and stiffer construction specifically to handle more weight on the tire. All other things equal, that produces a harsher ride and less comfort. Also the stiffer construction coupled with aggressive tread pattern often produces more noise as well. Not always, but often truck tires ride harsher and make more noise.

How Do You Use It?

Many vans used like cars can use passenger car tires. However, for hauling and towing trailers the car tires may not be the best or safest choice. What sometimes happens is the vehicle begins to be used more and more like a truck as the capabilities of the vehicle are learned. You may not buy a van to use as a truck. But over time it becomes more of a truck as you realize how handy that capability is. That’s where light truck tires fit.

Discount Tires For Vans

Online tire stores open up chances to save on tires. The online tire dealers survive based on at least three factors. They must have very informative, easy to use websites. They must have relatively low prices. They have to ship fast.

What that can do for you when you shop for van tires is give you an easy way to learn about tires available and an easy way to find a low price. Take that information with you when local shopping and you see how local selection and price compare to what you could get online.

Van tires must often deal with challenges that are somewhat unique. Often vans end up with roles more like a light truck than a passenger car. In many cases truck tires work well on certain types of vans.

Trucks are used to carry heavy loads and they cover long mileage therefore the recommended tires should have great puncture resistance capacity, offer ultra high performance on all terrain, should produce less noise and have minimal wear and tear. This will make riding comfortable. There are many types of truck tires that give the drivers variety to choose from depending on the truck distance, the weight they carry and puncture resistance capacity.

Bridgestone model are made up of heavy-duty rubber, rugged toughness and smooth wearing steer. They insure you ultra high performance on all terrain, minimize slip down on cornering and prevent serial breakdown and punctures. The wheels are durable and reliable. Michelin truck type are double size the normal ones. They are made of soft rubber to prevent over heating because saving fuel. They come in many varieties to suit all trucks and they are cost efficient and have strong scrub resistance. The superior bead design reduces mounting and de mounting damage and provides a long tread of life.

Good year model are made of heavy-duty rubber to minimizeize expenses and wear and tear. They have grip facility, produce less noise and have Dun seal technology that seals puncture immediately.

Semi-Trailers: Types And Maintenance

The Real Problem With DAF Truck Air Processing Units
Check out US Trailer Rental


A semi-trailer is a type of trailer where the front axle is absent. A significant proportion of its weight is carried by a road tractor, a front axle assembly which is detachable and termed a dolly, or even the tail belonging to another trailer.

A semi-trailer usually comes with a landing gear which supports it when uncoupled. Legs of the landing gear can be lowered for support.

A semi-trailer truck is a road tractor attached to a semi-trailer. It is also known as a semi or eighteen wheeler truck in the US. Typically, the fifth wheel of the truck connects to a semi-trailer Kingpin.


Each semi-trailer carries weight that is within the weight ratings limit displayed on the its identification/certification plate. There are two valid ratings: GAWR and GVWR

GAWR: The Gross Axle Weight Rating is defined as the structural capability of the lowest rated component of all running gear components, hub, wheels and drums, suspension and spring system, tires, axles, brakes, rims and bearings.

GVWR: The Gross Vehicle Weight Rating is defined as the structural capability of the eighteen wheeler when it is supported by the axles and the kingpin and when the load is distributed uniformly across the cargo space.

The semi-trailer will carry a load that is equal to the GVWR, less the eighteen wheeler weight. Any cargo loaded should be properly clamped down, braced and blocked so that shifting of loads does not occur. Further,it is also required to comply with local trucking laws.

Semi-Trailer maintenance

A semi-trailer should be properly maintained in order to obtain the performance it is built for.

Electrical system: All lights and reflectors should be cleaned. It should be ensured that all lights function properly. Broken reflectors and lights that are burned out should be promptly replaced. Wiring should not be frayed and must be correctly protected. Fuses should not be replaced by metal foils. It is advisable to use parts built by the manufacturer.

Brakes: They should be maintained properly. Eighteen wheeler brakes will function as long as they are not abused. Maladjusted brakes are the principal reason for a lengthier stopping distance. The brake life will be shortened if not maintained. It is better to connect with the manufacturer’s preventive maintenance service for an optimal load carrying experience.

Tires: They should not be over-inflated. Tires should be verified for correct inflation when they are cold. They should also be inspected for nail, stones and other foreign objects stuck in the rubber or between duals. It is to be ensured that the dual tires situated on any of the axle ends must have the same diameter. The total load on each tire should not exceed the figure specified by the manufacturer of the tire.

Correct usage of hand-holds and steps: Extreme caution must be adopted when using hand-holds and steps. They are subject to environmental as well as user damage. Ensure that components are maintained properly. They should be firmly attached to the body of the truck.

Safety defects

The semi-trailer manufacturer should be contacted immediately if a safety defect is found. You can also contact the relevant local administering authority. Defective trailers can prove to extremely hazardous on the road. Checking for safety defects must be treated as a priority exercise.

A Look Back at the Most Impressive Race Car Engines

Starter Clicks But Engine Does Not Turn Over - Tech in Trunk?

Did you know that race cars must have extremely powerful engines in order to be winners? Besides the aerodynamics that have been implemented and the modifications, the engine is what makes the car the ultimate winner.

Let’s start off with the famous Formula One Ferrari. One of the most famous engines in the F1 was the Ferrari V10 F1. It was a 3.0 litre, ten cylinder racing car that was responsible for 57 wins.

The Porsche Flat 6 is another racing vehicle that left an impression on the world. It was a 2.0 litre air cooled engine. The most recent version of this Porsche has received impressive results by winning many races over the years.

The Porsche Flat 12 has one of the biggest engines in the racing industry. There are two flat six engines packed into this car. It is a 4.5 litre engine which has 1500 horse power. You can imagine how cramped the driver must have been to make space for this massive machine.

The Mazda R26B 4-rotor might have been one of the craziest models in the racing industry. Having entered 21 races and only winning one might be a strange statistic. This one race was the LeMans and it made an impression as it was the only car that was not a conventional piston engine and it was a unique marque.

The BMW S14 was the start of the M-series. Winning the championship but winning no races, it was simply a 2.5 litre engine with only four cylinders.

The Audi R10-18 TDI has been through many changes over time but always had a memorable engine. Originally, this model was a petrol engine that had ten cylinders. This was entered into the LeMans race and won. However, the manufacturers decided to place a diesel engine with twelve cylinders and two turbos. Now, that is an amazing amount of power in just a single race car. Not even Formula One cars have a V12 Engine.

Ever race car has to be equipped with the finest mechanical and electrical parts. Races are there to prove the quality of the car before hitting the city streets. Racing cars also test how well an engine can cope under extreme conditions such as heat, rain and snow.

Racing tracks are also the best places for tyre manufacturers to test their new products. Rubber needs to withstand heat and friction over long periods of time and track day is the time to test it.

Off roaders love the feel of mud on their trucks. A muddy and sticky truck is a testament of their driving adventures and boosts their macho image.

However, a truck not equipped for an off road drive is like driving on the highway after a heavy rain. There is a slim chance that you will get out of the road safe and unhurt. Therefore, if you are a true off road driver, it is best that you equip your ride for the muddy road ahead. It is for your safety to equip your truck with mud tires.

Essentially, mud tires are designed to tread through muddy roads. They are equipped with special all-terrain feature to enhance their treading capacity. By definition, these are designed with larger, wider, and deeper lug to channel out mud out of the tread. This allows the lugs to clean itself so it could spin easily through muddy roads. Whatever type of road you drive through, these tires will provide you impressive traction and maximum stability. Similarly, when driving through wet, snowy, and icy roads, the tires sip water effectively for better road grip. The best types enhance the appearance of your truck for the real off road look and feel.

When choosing the best kind for your truck, there are several things you need to consider. After all, they are not all the same. So, if you are driving a two wheel or four drive trucks, you can take advantage of the driving comfort and enhance look it provides. You need to know some factors when deciding to use such.

• They do not come with mileage warranty. These tires work in a hostile environment; this is why they are not usually covered by factory warranty.

• Just like regular tires, you need to regularly rotate and balance them. Because they are heavier than regular tires, they need to be rotated often to reduce wear and lengthen its life.

• Alignment should also be done often. Due to the nature of the road these tires are used in, the front suspension can easily tire out. If the front wheels are out of alignment, it can easily cause them to wear out. So, be sure to check on the tires alignment regularly.

• Online auto shops offer good quality tires. Nevertheless, be sure to check for discounts and rebates, as there are online shops that offer good pricing rates and discounts. Also, be sure that the final product delivered to you is the same as the one specified in the site.

If chosen and maintained effectively, your mud tires can handle the worse roads and last for a long time significantly. So, be sure to choose wisely and carefully.
