Automobile tires are one of the crucial components of a vehicle, directly contacting the road surface and working together with the suspension system to absorb shocks during driving. They ensure good ride comfort and smooth driving, maintain excellent traction between the wheels and the road surface, and enhance the vehicle's traction, braking, and off-road capability.
