An all-weather all-season tire tread structure

Abstract

The invention discloses a tread structure of an all-weather all-season tire. The tread structure mainly comprises duplicate pitches; each pitch comprises a unit I, a unit II, a unit III, a unit IV and a unit V which are arranged in sequence; each unit adopts a dry-land pattern block and a wet-land pattern block which are alternately distributed in the vertical direction; the dry-land pattern blocks and the wet-land pattern blocks between every two adjacent units are also alternately distributed in the transverse direction, and part of the dry-land pattern blocks and the wet-land pattern blocks are staggered. The tread structure integrates the advantages of a summer tire and a winter tire, and can exert the excellent grip on dry land, wet land and a snowfield; on the dry land, the dry-land pattern blocks play a leading role; on the wet land or the snowfield, the wet-land pattern blocks play a leading role; the dry-land pattern blocks and the wet-land pattern blocks are alternately distributed in both the transverse and vertical directions, and simultaneously exert the grip when the all-weather all-season tire gets in contact with the ground; transverse and vertical grooves in each unit are communicated, and sludge discharge channels are formed among the paths, so as to improve the sludge discharge effect; the all-weather all-season tire has the characteristic of being excellent in grip, traction and sludge discharge performance.

Description

technical field [0001] The invention relates to the field of all-season tires, and more particularly relates to an all-weather all-season tire tread structure. Background technique [0002] Cars often need snow-specific tires when driving on snow and ice, and summer tires provide the best performance on dry roads. All-season tires eliminate the trouble of changing tires, taking into account the performance of tires on dry, wet and snowy ground. [0003] At present, the common all-season tires on the market are roughly divided into two categories. One is that the number of grooves is between that of summer tires and winter tires, and the groove density is evenly distributed in the circumferential direction; tire performance, and the other side has winter tire performance. But both types have their shortcomings. The first type has high rolling resistance on dry ground, but does not have sufficient snow performance on snowy roads; the second type has single-sided performance...
