Car radial tire tread pattern

Abstract

The invention relates to a car radial tire tread pattern. According to the car radial tire tread pattern, a central lengthwise circumferential pattern groove is arranged in the position of a central line of a tire tread, and the tire thread is divided into two bilaterally symmetrical parts by the central lengthwise circumferential pattern groove. Central pattern blocks, side pattern blocks and tire shoulder pattern blocks are respectively arranged on the left side and the right side of the central lengthwise circumferential pattern groove from the inner side to the outer side in sequence. The central pattern blocks are lengthwise integrated pattern blocks, main lengthwise circumferential pattern grooves are arranged between the central pattern blocks and the side pattern blocks so as to separate the central pattern blocks from the side pattern blocks, and auxiliary lengthwise circumferential pattern grooves are arranged between the side pattern blocks and the tire shoulder pattern blocks so as to separate the side pattern blocks from the tire shoulder pattern blocks. A transverse arc-shaped pattern groove is arranged between every two adjacent side pattern blocks so as to separate one side pattern block from the other. One end of the arc-shaped pattern groove starts from the main lengthwise circumferential pattern grooves, and the other end of the arc-shaped pattern groove stops in the tire shoulder pattern blocks. The arc-shaped pattern grooves are communicated with the auxiliary lengthwise circumferential pattern grooves. The pattern grooves and the pattern blocks are located and arranged in an optimized mode, and equalization of hardness of each pattern block of the tire is guaranteed, so that braking stiffness and cornering stiffness of the tire are enabled to be reasonably matched.

Description

technical field [0001] The invention relates to a tire tread pattern, in particular to a radial tire tread pattern. Background technique [0002] With the rapid development and popularization of passenger cars, the pace of tire pattern replacement is accelerating, and the functional subdivision and special features are more prominent, such as all-weather tires, summer tires, winter tires, snow tires, etc. . The design of tire tread pattern generally adopts the combination of horizontal pattern and longitudinal pattern. In addition to the wear resistance, grip, drainage and other performances, the design of the pattern should also consider the aesthetics of the tire, and require the tire to have a stable Starting and braking performance. Studies have shown that under the same conditions, the wear resistance and braking performance of the transverse pattern is better than that of the longitudinal pattern; however, the lateral slip of the transverse pattern is greater than th...

AI Technical Summary

Problems solved by technology

The quality of tread pattern design is the most important factor affecting the handling performance of tires on snow, ice and dry roads, but weighing tire performance under several road conditions has also become a difficult problem in the design stage of tire tread pattern. Tires have good performance on icy roads or snowy road conditions, but it is difficult to greatly improve the handling performance on icy roads and snowy road conditions at the same time
