Embodiment Construction

[0062] Based on the above technical features, the main functions of the tire with enhanced drainage performance of the present invention will be clearly presented in the following examples.

[0063] Please see first figure 1 and figure 2, is to disclose the embodiment of the present invention can enhance the drainage performance of the tire 1, in this embodiment is a motorcycle tire, including a tread portion 11 and two tread ends 12. There are a plurality of first concave grooves 13 on the tread portion 11 , and the plurality of first concave grooves 13 are alternately distributed on the tread portion 11 . Preferably, the tread portion 11 is further provided with a plurality of second concave grooves 14 and a plurality of shallow grooves 15 arranged at intervals. The aforementioned first groove 13 may be in the shape of an O, while the aforementioned shallow groove 15 may be in the shape of an L and run through two adjacent aforementioned second grooves 14 . Such as ima...

Abstract

The invention discloses a tire with enhanced drainage ability. The tire includes a tread part, the tread part comprises two tread ends, a tread center line and a half tread unfolding width are definedbetween the two tread ends, a plurality of first grooves are formed in the tread part, the plurality of first grooves are distributed on the two sides of the center line of the tread in a staggered manner, and the plurality of first grooves are all arranged in a first area of which the unfolding width of the half tread is between 10% and 90%. Each first groove is provided with a first groove section and a second groove section which are connected with each other, wherein the first groove section is relatively close to the tread center line, the second groove section is relatively close to thetread end, an included angle between a first extension line of the first groove section and the tread center line is between 9 degrees and 12 degrees, and an included angle between a second extensionline of the second groove section and the tread center line is between 50 degrees and 55 degrees.

Description

technical field [0001] The invention relates to a tire, especially a tire that can enhance drainage performance. Background technique [0002] In order to make the tire adaptable to wet and slippery road surfaces, a tread structure is formed on the tread of the tire, so as to use the tread structure to assist drainage. [0003] How to provide a better design for the groove shape, size, quantity, distribution position, etc. of the tread structure, so that the tire can take into account different performances such as grip, drainage, guidance, and comfort, has been the focus of all walks of life. direction of research and development. [0004] Regarding tires with improved drainage performance, for example, there are "motorcycle pneumatic tires for racing" in the Chinese Invention Patent Announcement No. CN103991338B, and the "motorcycle tires" in the Chinese Invention Patent Announcement No. CN102574428B. The treads of the tires mainly have The pattern main grooves are arran...
