Firstly, tires are the carrier of force transmission between vehicles and the road surface, transmitting driving force, braking force, steering force, etc. through tires, thus achieving the driving, braking, steering and other operations of automobiles.

Secondly, support the vehicle load. The load on the vehicle causes the tire to sink until the average pressure on the tire ground area reaches a balance with the inflation pressure inside the tire.

Thirdly, reduce and absorb the vibration and impact force during the driving process of the car, and avoid early damage to car components caused by severe vibrations. Simultaneously adapt to the high-speed driving state of the vehicle and reduce driving noise, ensuring safety, comfort, handling stability, and fuel economy during driving.
