They can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. 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. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
