Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation. Foam wheels refer to wheels made of plastic materials through injection foaming, which have stable dimensions and a shrinkage rate of less than 1%.
