Tires are ring-shaped elastic rubber products that are grounded and rolled on various vehicles or machinery. It is usually installed on metal rims, which can support the body 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 temperatures when driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, high abrasion resistance and flexural resistance, as well as low rolling resistance and heat generation are required.
