All-weather SUV radial tire

Abstract

Provided is an all-weather SUV radial tire. The all-weather SUV radial tire comprises a first pattern part, a second pattern part, a third pattern part, a fourth pattern part and a fifth pattern part,wherein the first pattern part, the second pattern part, the third pattern part, the fourth pattern part and the fifth pattern part are partitioned by four vertical grooves. By adopting a certain tire sea-land ratio of a braking area, a cutter groove reinforcement design and the like, the braking performance and off-road traction performance under the influence of ice and snow of the all-weatherSUV radial tire are improved effectively. Under the condition that the total sea-land ratio is not changed, the total area of pattern blocks in the braking area and the total area of the braking areaare designed to be in the range from 69% to 71%, and the braking performance can be improved without influencing the performance of a snowfield. According to different pattern parts, three different cutter groove styles are adopted, different types of reinforcing blocks are additionally arranged on different cutter grooves to improve the rigidity of the pattern blocks, and by simulating the anglesand proportions of the reinforcing blocks and obtaining the optimal angle and the optimal volume proportion according to different parts, the braking performance is improved to the greatest extent onthe basis of effectively ensuring the ice-snow resistance performance and uniform abrasion; by combining with an under-shoulder chain-shaped pattern design, the lateral traction performance in the snowfield is improved, the braking performance is effectively improved, and the driving safety is improved.

Description

technical field [0001] The invention belongs to the field of automobile tires, in particular to an all-weather SUV radial tire. Background technique [0002] All-weather SUV radial tires are aimed at various climatic conditions and different road conditions. Compared with summer tires, they still retain better traction performance under light snow conditions in winter, and at the same time have better performance on various road surfaces, including complex road surfaces in the wild. Strong grip. All-weather SUV radial tires are popular among users because they do not need to replace winter tires in winter or in light snow weather and can be used on various road surfaces, which reduces user costs and expands the scope of use. [0003] The traditional all-weather SUV radial tire tread design considers the winter traction performance, and generally adopts the method of adding small sipes to the tread block to improve the snow traction performance. Insufficient, the braking pe...
