Background

At present, with the continuous development of the automobile industry, the requirements of people on the automobile performance are higher and higher, and the functions and the purposes of the tires are subdivided and refined more so as to meet the use requirements of people on different special vehicles. In particular, the tire can meet the requirements of good comprehensive properties such as economical wear resistance, comfort performance, control stability, wet skid resistance, drainage performance, durability and the like.

In the existing tire, aiming at different types of cars, the requirements on the patterns of the tire are different, such as:

a longitudinal pattern tire having low noise, low resistance, and providing better drainage performance for the tire, but such tires have relatively weak braking performance;

the transverse pattern tyre has the pattern accounting for 78% of the running area, high traction and braking performance, high wear resistance, high rolling resistance, and is suitable for asphalt, cement, sand and gravel road, etc. and the tyre has the disadvantages of poor water draining performance, great tyre noise, easy wear, high oil consumption, poor high speed performance and operation performance.

The block pattern tyre has excellent control and stability on snow and wet road and good drainage performance in rainy days, and has the defects of independent block structure and poor wear resistance.

Therefore, a tire pattern needs to be designed, so that the comprehensive performances of the tire, such as economic wear resistance, mute performance, comfort performance, control stability, wet skid resistance, drainage performance, durability and the like, can meet the demands of customers and meet the demands of markets.
