Main Tire Functions
Tires are designed to support the weight of the vehicle, absorb road shocks, transmit traction, torque and braking forces to the road surface and maintain and change the direction of travel. To fulfill these four basic functions, tires are made of resilient rubber and filled with compressed air. The inner tube in a tire is used for the maintenance of proper air pressure, but it alone cannot retain air pressure high enough to support vehicle load nor is it durable enough to withstand damage or shocks
The carcass protects the inner tube inflated with high-pressure air and supports the vehicle load. Its thick rubber layer, which is attached to the part of the tire that meets the road, can withstand exterior damage or wear. Tire tread patterns are chosen according to car movement and stability needs.
A solid structure is necessary to ensure tires are securely assembled onto rims. With growing demand for gentrified high-performance vehicles, a variety of tires with more complex functions and performance are now being developed.
