The role of industrial solid tire surface pattern

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 pattern design on the tire surface improves the grounding 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 blocks can produce greater tangential elastic deformation. As the tangential force increases, the tangential deformation becomes larger, and the "friction effect" of the contact surface is also increased, thereby controlling the slipping or slipping trend of the tread and 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 surfaces, the effect of molecular gravity, and the micro-cutting effect of the small-size micro-protrusions on the road surface. However, the main role is still Elastic deformation of the pattern block.

The use of different pattern designs also greatly affects the overall performance of the tire, and different patterns represent different product positioning. For icy and snowy roads, cement roads and better gravel soil roads, tires with common tread patterns and sand-gravel roads should be used. Cars often drive on asphalt sea concrete roads, which can improve the drainage capacity when passing wet roads and improve the friction of tires on bad roads. The production of various patterns of different shapes is conducive to tire heat dissipation and prevents lateral slippage of automobile tire treads. The function of the pattern is to increase the adhesion between the tire and the ground. The tire with an off-road tread pattern, loose soil or other roads with poor road conditions, PILOTSPORT3 is a sporty pattern) Usually a "comfortable pattern" in car tires The design pays more attention to reducing the noise generated by the pattern blocks hitting the road surface.
