Tires are ground rolling, toroidal elastic rubber products that are assembled on various vehicles or machinery. In 1845, R.w. Thomson, a Scottish-trained civil engineering technician, invented the pneumatic tires, and he was awarded the patent of the British government on the subject of “The Wheels of Carriage and Other Vehicles.” In December 10th the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims to support the body, cushioning external impact, achieving contact with the road surface and ensuring the vehicle's driving performance. Tires are often used under complex and demanding conditions. They are subjected to various deformations, loads, forces, and high and low temperatures when traveling. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used in tire production. It can be seen that the ability of tires to use rubber is very similar.
