Tires are circular elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. They support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain driving performance.

Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability.
