Abstract

The invention discloses an all-weather tire tread structure, which includes a carcass, and the center of the carcass is provided with an annular longitudinal main groove; both sides of the longitudinal main groove are uniformly provided with transverse main grooves along the rolling direction of the tire , and the transverse main grooves corresponding to the horizontal positions on both sides of the longitudinal main groove have an "in" shape structure; the longitudinal transverse main grooves are provided with single-guided transverse pattern blocks; the single-guided transverse The pattern block is provided with straight steel thin grooves, single curved steel thin grooves and double curved steel thin grooves outwardly from one end close to the longitudinal main groove; the middle of the double curved steel thin grooves is Features crossed straight steel pieces. Compared with the prior art, the present invention has the beneficial effects of: overcoming the single defect of the tire performance in the prior art, satisfying the performance of dry and wet grip while having winter snow performance, and also having low noise and low rolling resistance.

Description

technical field [0001] The invention relates to the field of tires, in particular to an all-weather tire tread structure. Background technique [0002] With the popularization of modern urban vehicles, people have higher and higher requirements for tires. Snow tires are used in winter, and summer tires are replaced in summer. Frequent tire replacement brings a lot of waste of time and energy to people. In order to meet the market demand, all-season tires that can adapt to different weathers and climate changes throughout the year are needed. They must not only meet the dry grip performance, wet grip performance, good noise performance, but also meet the snow performance. [0003] At present, in some foreign regions such as Canada, it snows for a long time in a year, and the government departments require that all tires be replaced with all-weather tires in order to increase the safety factor. It also accelerated the development of all-season tires. Contents of the inventi...
