The Role of Tires in Vehicles:

Tires are circular, elastic rubber products that are fitted to various vehicles and machinery. Typically mounted on metal rims, they support the vehicle's weight, absorb external shocks, provide contact with the road, and ensure the vehicle's performance.

Tires operate under complex and demanding conditions. They endure various deformations, loads, forces, and extreme temperatures while in motion. Therefore, they must possess high load-bearing capacity, traction, cushioning, wear resistance, and flexibility, along with low rolling resistance and heat generation.

The automotive industry consumes half of the world's rubber production, highlighting the significance of tires in the rubber industry.
