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.
