Abstract

The invention discloses a tire tread structure of a pneumatic tire of a motorcycle. A tire tread comprises a plurality of main pattern groove groups which are formed in a staggered manner by using the center of the tread as a symmetry center, and each main pattern groove group comprises a first main pattern groove and a second main pattern groove which are formed in a tilt manner from the inner side of the tire tread to the outer side, wherein stone removing openings with irregularly polygonal edges are respectively formed in the front ends, the middle parts and the tail ends of the first main pattern groove and the second main pattern groove. The left sides and the right sides of the longitudinal main pattern grooves formed in the tire tread are arranged alternately, so that the guide performance and the water drainage performance of the tire are ensured. In order to improve the situation that the tire has better traction performance and stone removing functions on non-paved roads, the stone removing openings are formed in the front ends, the middle parts and the tail ends of the patterned main grooves, so that the rigidity of the tire tread can be ensured, and the stone removing is facilitated; at the same time, the stone removing openings are provided with the irregularly polygonal edges, the ingredients of the edges are high, so that the tire has better traction performance when the motorcycle is driven on the non-paved roads.

Description

technical field [0001] The invention relates to a motorcycle pneumatic tire, in particular to a motorcycle pneumatic tire tread structure for paving or non-paving roads. Background technique [0002] Such as Figure 8 , Figure 9 In the past, pneumatic tires for motorcycles, in order to improve tire guiding and drainage performance, the tread 20 generally adopts a streamlined pattern design, CL is the center line of the tread, the streamlined pattern includes the main groove 21 and the auxiliary groove 22, and the main groove 21 adopts a large The pattern groove is designed with high span and inclination angle. The groove width W5 of the pattern main groove 21 is gradually widened from the tread to the tire shoulder. The inclination angle Ψ of the pattern main groove 21 is set to be small. 212 is composed of smooth arc lines or straight lines. A secondary pattern groove 22 is added between the pattern main groove 21 and the pattern main groove 21. The inclination direction ...
