Functions of Tires

Tires play an important role as an automobile component. Despite its simple appearance, a tire differs from other parts of a vehicle, in that its roles are multiple and varied.

Tires play an important role as an automobile component. Many parts may make up a car but usually one part is limited to one function. Despite its simple appearance, a tire differs from other parts in that it has numerous functions.

Thus, a tire supports the weight of the car, reduces the impact from the road and at the same time, transmits the power to propel, brake and steer on the road. It also functions to maintain a car’s movement. In order to complete such tasks, a tire must be structured to be a resilient vessel of air.

A tube is used to maintain its major function of maintaining air pressure but a tube alone cannot maintain the high pressure needed to withstand the great weight. In addition, the tube lacks the strength to withstand all of the exterior damage and impact from driving on the road. The carcass is entrusted with this function.

The carcass is an inner layer that protects the tube that contains the high-pressure air and supports vertical load. A thick rubber is attached to the parts that meet the road to withstand exterior damage and wear. Tread patterns are chosen according to car movement and safety demands. A solid structure is necessary to make sure the tires are securely assembled onto rims.

According to improvements in automobile quality and capability as well as the diversification of usage, the capabilities and performance of tires are becoming more complex and diversified.
