Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the utility model and not to limit the scope of the utility model.

Unless defined otherwise, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.

As shown in FIG. 1, the all-terrain tire comprises a tire body and tread blocks arranged on the outer surface of the tire body, wherein the tread blocks are composed of crown blocks arranged in the crown central area of the outer surface of the tire body and transverse traction blocks arranged on the shoulder parts on two sides of the outer surface of the tire body;

the crown block is composed of crown block I1, crown block II2 and crown block III3 which are different in shape, the traction block is composed of traction block I4 and traction block II5, traction block I4 and traction block II5 are arranged at intervals, and the crown block I1, crown block II2 and crown block III3 are closely arranged corresponding to the shoulder part of the traction block I4. The crown block I1, the crown block II2 and the crown block III3 are quadrangles, pentagons, unfilled corner pentagons or octagons and the like, and are arranged closely to increase the grounding area of the blocks and improve the operation stability and the wear resistance.

As an improvement of the embodiment, zigzag grooves are arranged on the crown block I1, the crown block II2 and the crown block III3, and the groove depth does not exceed 1/2 of the pattern crown depth, so that the drainage and the gripping performance of the crown pattern are improved.

As an improvement of the embodiment, the transverse widths of the crown block I1, the crown block II2 and the crown block III3 occupy the width of the driving surface and are not less than 1/3, so that the ground contact area is increased, and the steering property, the steering stability and the wear resistance of the tire are improved when the tire is driven on a hard base road surface such as a highway.

As improvement of the embodiment, the traction pattern blocks I4 and the traction pattern blocks II5 are transverse pattern blocks which are close to the crown part and have large longitudinal dimension and small shoulder longitudinal dimension, the width of the traction pattern blocks I4 and the traction pattern blocks II5 on the driving surface is not less than 1/5 of the whole driving surface width, the traction pattern blocks I4 and the traction pattern blocks II5 are adjacent and are alternately arranged in the circumferential direction, the gripping performance and the traction performance of the tire are guaranteed, and the driving performance on the off-road is improved.

As an improvement of the embodiment, the widths of the traction block I4 and the traction block II5 at the driving surface part are equal or slightly different, the traction block I4 and the traction block II5 are divided into 1-4 blocks (3 blocks in the embodiment) by the longitudinal grooves 6 and the side grooves 7, and the self-cleaning performance and the aesthetic property of the pattern are improved.
