1.Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. .

2.They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used in complex and harsh conditions.

3.They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance.

4.At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.
