Tire is a ring-shaped elastic rubber product with grounding rolling assembled on various vehicles or machinery. Usually installed on the metal rim, it can support the vehicle body, buffer the external impact, realize the contact with the road and ensure the driving performance of the vehicle.
Tires are often used in complex and harsh conditions. They bear various deformation, load, force and high and low temperature during driving. Therefore, they must have high bearing performance, traction performance and cushioning performance. At the same time, it is also required to have high wear resistance and flexion flexibility, as well as low rolling resistance and heat generation.
