Tire introduction
Tire is a round elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. Usually installed on the metal rim, it can support the car body, buffer 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 performance, traction performance and cushioning performance. At the same time, it also requires high wear resistance and bending flexibility, as well as low rolling resistance and heat generation.
As the only part of the car that touches the ground, the performance of tires directly affects the safety of drivers and passengers. The importance of tire performance can be imagined, so all countries have made clear requirements for tire safety performance. With the rapid development of automobile industry, consumers pay attention to the safety performance of tires and the comfort of the whole vehicle.
