Special tire tread pattern structure of motorcycle for race in rainy day

Abstract

The invention relates to a special tire tread pattern structure of a motorcycle for race in rainy day, which is characterized in that the tire surface comprises a central groove through a circumferentially continuous bar-shaped straight groove design, inclined main grooves and inclined auxiliary grooves arranged by taking the tire surface as a center in a symmetrical and interlace mode; the bottom of the central groove is arranged along a circumferential direction with an equant mode to form wave tooth; the inclined main groove extends from the center of the tire surface to tire shoulder in an extension manner, the groove width is gradually increased from the tire surface center to the tire shoulder; multi-strip inclination auxiliary grooves are arranged between adjacent inclined main grooves at same side, the inclination direction of each inclined auxiliary groove and the inclined main groove is arranged in an opposite way, and each inclined auxiliary groove is communicated to at least one of the inclined main groove. Through a special design of the central groove bottom and the inclined auxiliary groove, the traction performance and gripping performance on wetland can be increased when the motorcycle drives on pavement at high speed in rainy day.

Description

technical field [0001] The invention relates to a motorcycle tire, in particular to a tread pattern structure of a special motorcycle tire for racing in rainy weather. Background technique [0002] In the past, motorcycle tires had oblique main grooves and auxiliary grooves on the tread. The main grooves and the auxiliary grooves were in the same direction, and the overall land ratio of the pattern was large. When driving on wet roads, drainage and wear performance could be ensured. [0003] In recent years, motorcycles have been gradually upgraded from people's means of transportation to a tool for professional drivers. The tires used by general motorcycles for transportation can no longer meet the performance required by professional drivers, especially in wet and rainy days. When driving at high speed on the road, if you use conventional motorcycle tires, the traction performance will be poor because the main pattern groove and the auxiliary pattern groove are in the same...

AI Technical Summary

Problems solved by technology

[0003] In recent years, motorcycles have been gradually upgraded from people's means of transportation to a tool for professional drivers to use in competitions. The tires used by general motorcycles for transportation can no longer meet the performance required by professional drivers' competition tires, especially in rainy days and wetlands. When driving at high speed on the road, if you use conventional motorcycle tires, the traction performance will be poor due to the main tread groove and the auxiliary tread groove in the same direction, which will affect the race performance of the driver

In addition, due to the high land-to-land ratio, when turning at high speed in rainy days, the lack of grip of the tires will cause slippage and cause a crash accident, which will affect the personal safety of the driver.
