First, the tire is the carrier of force transmission between the vehicle and the road surface, and the driving force, braking force, steering force, etc. are transmitted through the tire, so as to realize the driving, braking, steering and other operations of the car.
Second, support the vehicle load. The load on the vehicle causes the tires to sink until the average pressure in the ground contact area of the tires is balanced with the inflation pressure inside the tires.
Third, reduce and absorb the vibration and impact force of the car during driving, and avoid early damage caused by violent vibration of auto parts. At the same time, it adapts to the high-speed driving state of the vehicle and reduces the driving noise to ensure the safety, comfort, handling stability and fuel economy of driving.
