Tires are ground-rolled, circular elastic rubber articles that are assembled on a variety of vehicles or machinery. Usually mounted on a metal rim, it can support the body, cushion external impact, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and demanding conditions. They are subjected to various deformations, loads, forces and high and low temperatures during driving, and therefore must have high load bearing properties, traction properties and cushioning properties. At the same time, it is required to have high wear resistance and flex resistance, as well as low rolling resistance and heat build-up. Half of the world's rubber consumption is used in tire production, showing the ability of tires to consume rubber.
