Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. Usually installed on metal wheels, it can support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they bear various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it also requires high wear resistance and flexural flexibility, as well as low rolling resistance and heat generation.
