Tire pattern knowledge

Tires, as the only medium for vehicles to contact the ground, are responsible for important tasks such as load bearing, braking and driving safety.
And when the vehicle is driving on the road, the area of ​​the tire in contact with the ground is not much larger than the area where the soles of our shoes are in contact with the ground when we walk on the road. With such a small contact area, such an important and complicated task needs to be completed. Have you ever wondered what the most important factors are?

To tell you frankly, it is the tire pattern that everyone doesn’t care about.
Generally speaking, a tire pattern is a groove composed of various longitudinal, lateral, and oblique directions on the tire tread. Don’t look at these horizontal and vertical patterns are messy, in fact, they have a clear division of labor.

Because the longitudinal pattern has the characteristics of longitudinal continuity, it mainly undertakes the function of draining water in rainy weather, and is also very helpful for the heat dissipation of the tire, but the grip is insufficient. The horizontal pattern has a greater gripping ability, which can make up for the congenital defects of the longitudinal pattern.

What is a vertical pattern?

The longitudinal pattern of the tire is the pattern arranged in accordance with the circumference of the tire. This pattern usually has several on a tire.

What is a horizontal pattern?

In contrast to the longitudinal pattern, this pattern is longitudinally disconnected and laterally continuous. This design makes the tire’s transverse surface rigidity high, and the friction and braking effect are better.
Mixed tread tires

The longitudinal pattern on the tire mainly plays a role of rapid drainage, but it will lead to insufficient grip of the tire; while the transverse pattern on the tire has a higher grip capability, but the drainage capacity and guidance are not good. Therefore, the engineers who designed the tires mixed the two patterns together and reached a “tacit understanding”, so that the longitudinal pattern that can provide fast drainage in the middle and the transverse pattern that provides grip on the shoulders are combined into a perfect situation, so that the mixed patterns Was born.

Having said that, what role does the tire pattern play?

In a nutshell, it has the following functions:

  1. Increase the friction between the tire and the ground;
  2. Reduce tire noise and enhance comfort;
  3. Heat and drain the tires;
  4. Improve vehicle handling performance;
  5. Beautiful, enhance visual effect.
