Problems solved by technology

However, since the length of the grooves or sipes is increased, the rigidity of the land part of the four-season tire decreases, so there is a problem that the steering stability of the four-season tire on dry roads deteriorates.
In this way, the improvement of braking performance on ice and snow roads and the assurance of handling stability on dry roads or wet roads are interfering with each other, so it is difficult to balance both.

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] A snow tire, comprising a tread 1 and shoulders 2 located on both sides of the tread 1, extending laterally along the tire tread, and a plurality of pattern grooves are evenly arranged along the tread circumferential direction, the pattern grooves are opposite to the tread pattern The left and right sides of the center line have the same shape and size, and are arranged alternately. The pattern grooves include V-shaped grooves 3 arranged on the tread. The tire shoulder 2 extends in the width direction of the tire. The present invention replaces the traditional sipe pattern or sipe groove by arranging the V-shaped groove 3 thereon, so that the snow tire has be...

Abstract

The invention provides a snow tire. The braking performance of the snow tire is improved without affecting the operation stability. The snow tire comprises a tire tread and tire shoulders positioned on the two sides of the tire tread; multiple pattern grooves extend in the transverse direction of the tire tread and are uniformly arranged in the circumferential direction of the tire tread; the leftand right shapes, structures and dimensions of the pattern grooves relative to the central line of a tire tread pattern are consistent and the pattern grooves are alternately arranged relative to thecentral line of the tire tread pattern; the pattern grooves comprise V-shaped grooves formed in the tire tread; two grooves forming each V-shaped groove extend to the tire shoulders on the two sides;and the tire shoulders extend out in the width direction of the snow tire.

Description

technical field [0001] The invention relates to a snow tire and belongs to the field of radial tires. Background technique [0002] Snow tires are positioned to be used in severe weather such as ice and snow in winter. Although the maintenance time in winter is not long, the requirements for tire safety in this kind of weather should be higher. In ordinary weather, ordinary all-season tires are generally installed on cars, and ordinary all-season tires are more difficult to brake and control when driving on icy and snowy roads, resulting in reduced safety performance and frequent traffic accidents. Therefore, timely replacement of snow tires has a certain guarantee for the safety of the car. [0003] In the traditional technology, in order to make the four-season tire have good braking performance on ice and snow roads, people set a plurality of grooves or sipes on the tread portion to form the entire land portion of the four-season tire. In recent years, with the improvem...
