Abstract

The invention discloses a tread structure of a pneumatic tire for a motorcycle. A 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, wherein first auxiliary fine diamond pattern grooves are formed among the main pattern groove groups, and each first auxiliary fine diamond pattern groove comprises a fine diamond part which is provided with a plurality of tangent planes and a fine groove which is connected with the fine diamond part. The fine diamond parts and the fine grooves of the auxiliary fine diamond pattern grooves are designed to be in mutual connection, so that water films can be effectively broken, the water drainage performance of the tire is effectively improved, and the wet land gripping performance of the tire is improved.

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] like 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 of ...
