Problems solved by technology

[0003] In recent years, with the warming of the global temperature, the ice and snow covered roads in some areas have decreased in winter. Therefore, the demand for driving performance on dry and wet roads under non-snow road conditions in winter driving has continued to increase. However, due to the existing all-season tires focusing on Snow driving performance, so it cannot meet the actual road conditions of all-season tires at this stage.

Abstract

The invention discloses a pneumatic tire, the main tread has a plurality of main grooves extending from the two side edges of the main tread to the middle of the main tread, and tire strips contacting the ground are formed between two adjacent main grooves. The circumferential centerline of the tread is taken as the reference, and the main grooves located on the same side of the circumferential centerline are parallel and evenly distributed along the circumferential direction of the main tread, and the main grooves located on both sides of the circumferential centerline are arranged in a dislocation and intersect. The inner ends of two main grooves on the opposite side of the above-mentioned circumferential center line and adjacent in the circumferential direction of the main tread intersect at the middle of the main tread; The straight line extending axially is the axial reference line, then the distance between the centerline of the main groove and the axial reference line increases from the outer end to the inner end of the main groove, and the width of the main groove is from the outer end to the inner end decrease. The pneumatic tire has excellent driving performance in dry, wet and snowy road conditions, and can fully meet the driving needs of the vehicle in four seasons.

Description

technical field [0001] The present invention relates to the technical field of pneumatic tires, more specifically, to a pneumatic tire. Background technique [0002] In some European countries in the frigid or sub-frigid zone and the northeastern region of our country, in order to ensure stable driving in each season, the tires of vehicles will be replaced twice a year, that is, summer tires are used in summer and autumn, and tires are given to tires before winter. The vehicle is replaced with winter tires to improve the winter performance of the vehicle. With the continuous improvement of user requirements, most tire manufacturers have developed all-season tires, which can simultaneously meet the driving needs of vehicles on dry roads, wet roads, and ice and snow roads. [0003] In recent years, with the warming of the global temperature, the ice and snow covered roads in some areas have decreased in winter. Therefore, the demand for driving performance on dry and wet road...
