However, with such setting, the pattern land ratio in the straight ground area is relatively large, the pattern rigidity is strong, the edge component of the pattern is low, and the traction performance is not good. In addition, the grooves in the cornering area are wide, the pattern land ratio is low, the pattern rigidity is weak, and the roll characteristics are not sufficient. unable to corner effectively

Embodiment
[0027] Such as Figure 2 to Figure 7 As shown, the tire tread 1 is composed of pattern main grooves 10 and pattern auxiliary groove groups 20. The pattern main grooves 10 are alternately distributed on the left and right sides of the tread 1, which can ensure drainage performance and improve tire traction performance. The pattern main groove 10 extends obliquely downward from a position close to the center of the tread toward the tire shoulder, and the pattern main groove 10 is formed by an upwardly convex arc-shaped groove 12, a downwardly convex arc-shaped groove 11, and a pattern short groove 13. The convex and concave directions of the downward convex arc groove 11 and the upward convex arc groove 12 are opposite, which can ensure the drainage performance, and improve the traction performance by utilizing the edge components of the forward and reverse grooves. The short pattern groove 13 extends obliquely downward from the front end of the downward convex arc-shaped groove...

The invention discloses a tread structure of a pneumatic tire for a two-wheeled vehicle. The tread comprises main pattern grooves distributed in the left side and the right side of the tread in a crossed manner and auxiliary pattern groove groups connected between the upper and lower adjacent main pattern grooves, wherein the main pattern grooves obliquely extend downwards in the direction of shoulders from the position close to the center of the tread, each main pattern groove comprises an upper convex arc-shaped groove, a lower concave arc-shaped groove and a short pattern groove which are connected into a whole, and each auxiliary pattern groove group comprises a first auxiliary pattern groove, a second auxiliary pattern groove and a third auxiliary pattern groove which are sequentially distributed from the center of the tread to the outside. With the adoption of the tread structure, the traction performance and the anti-roll performance of the tire can be improved while the water drainage performance is guaranteed.
Description
technical field [0001] The present invention relates to a tread structure of a pneumatic tire for two-wheel vehicles. Background technique [0002] Such as figure 1 As shown, in the past pneumatic tires for two-wheeled vehicles, the tread 1' is composed of the pattern main groove 10' and the pattern auxiliary groove (11', 12') arranged obliquely, and the pattern main groove 10' extends from the tread center to the shoulder Slanted extension ensures drainage performance. In order to disperse the rigidity of the pattern blocks and improve the straight-running control and cornering wet-ground grip performance, inclined pattern sub-grooves are added between the adjacent pattern main grooves 10'. The 12' wide pattern auxiliary groove design is adopted, and each pattern auxiliary groove is designed to be inclined in the same direction as the pattern main groove to ensure drainage performance. However, with such setting, the pattern land ratio in the straight ground area is rela...
