Pneumatic tire tread pattern structure for motorcycle

Abstract

The invention discloses a tread pattern structure of a pneumatic tire for motorcycles. The tire tread is composed of several pattern units arranged symmetrically with the center line of the tread and arranged in a staggered manner. Two "h"-shaped pattern main grooves, wherein the long side of each pattern main groove "h" shape includes the first fold line extending from the center of the tread to the shoulder, and the inclination angle relative to the center line of the tread increases from small to large ditch, the second folded line ditch and the third folded line ditch, the fourth folded line ditch and the fifth folded line ditch form the horizontal and short sides of the "h" shape, and the fourth folded line ditch runs through the third folded line ditch and the fifth folded line ditch; The folding line groove and the fifth folding line groove extend from the middle of the tread to the tire shoulder. Each folded line groove extends obliquely from the center of the tread to the shoulder, which can ensure the guiding and drainage performance. The inclination angle of each folded line groove relative to the tread center line is set from small to large. Using the change of the angle, the edge composition of the pattern groove is improved, and the traction and wet grip.

Description

technical field [0001] The invention relates to a pneumatic tire for a motorcycle, in particular to a tread pattern structure of a pneumatic tire for a scooter. Background technique [0002] In recent years, large scooters have become more and more popular among consumers. In order to ensure the guiding and drainage performance of pneumatic tires for large scooters, cooperation with figure 1 As shown, the tread pattern 1' is generally composed of streamlined inclined grooves. In order to improve the traction performance of the tire and improve its edge composition, the edge of the main groove 21' is designed with a concave-convex drop, but the main groove 21 is set in this way. 'There is a problem of different sizes of the ditch width, which reduces the drainage performance to a certain extent. In addition, in order to improve the wet grip performance when cornering, an inclined auxiliary groove 22' is added between the main grooves 21' to increase the contact area of ​​the...
