Tires are usually installed on metal rims, which can support the car body, cushion the external impact, achieve contact with the road surface and ensure the driving performance of the vehicle.

Tires are often used in complex and harsh conditions. They are subjected to various deformations, loads, forces and high and low temperatures during driving, so they must have high bearing capacity, traction performance and cushioning performance. At the same time, it also requires high wear resistance and flexibility, low rolling resistance and heat generation. Million car purchase subsidy
