The role of tire pattern

In short, the main function of the tire pattern is to increase the friction between the tread and the road surface to prevent the wheel from slipping, which is the same as the sole pattern.

The tire pattern improves the ground contact elasticity of the tread. Under the action of the tangential force (such as driving force, braking force and lateral force) between the tread and the road surface, the pattern block can produce greater tangential elastic deformation. As the tangential force increases, the tangential deformation increases, and the "friction effect" of the contact surface also increases, thereby inhibiting the tread slipping or slipping on the road surface. 

This largely eliminates the shortcomings of non-patterned (light tread) tires that are easy to slip, making the car performance related to the friction between the tire and the road surface-dynamic, braking, steering and driving safety There is a reliable guarantee for normal performance. Studies have shown that the factors that produce the friction between the tread and the road surface also include the adhesion between the two sides, the molecular gravitational effect, and the new micro-cutting effect of the pavement's small rain on the surface of the tread. However, its main role is What is still the elastic deformation of the pattern block.
