What Are Tires?

Tires are the circular, cylindrical or ring-shaped components used for the transportation of people or goods. They are composed of various materials like rubber, metals, plastics and fabrics. These tires are designed for specific purposes and applications.

The purpose of a tire is to provide traction and a grip to the road surface. This is done by tread rubber that is designed to resist wear, abrasion and friction heating. It is also able to maintain its shape when the tire is driven at high speed.

Tires are constructed of many materials, such as natural rubber, styrene-butadiene copolymer, nylon, polyester, rayon, steel, aluminum and plastic. Aside from these materials, tires can contain several other specialized components.

Aside from the tread, the sidewall is another crucial part of the tire. The sidewall is an outer layer that protects the tire from curbs and road impact.

The inner liner is an air-tight layer of synthetic rubber that helps maintain the pressure of the tire. Another layer is called the carcass. Above the inner liner, the carcass is made of thin textile fiber cords that are bonded to the rubber.

Another important feature of tires is the undertread. The undertread is a cushion that absorbs shock and breaks water tension on the road surface.

The sidewall is a rigid, stiff rubber that protects the tire from the road and curbs. The tire is then loaded with air. When it is inflated, the air moves through the tire to the wheel.
