Tire face tread pattern structure

Abstract

The invention discloses a tire face tread pattern structure. A plurality of thread pattern block units are arranged in the circumferential direction of the periphery of the tire face at intervals. Thetread pattern block units comprise protruding tread pattern blocks arranged on the tire surface. The protruding tread pattern blocks are arranged to be a first center block, a second center block anda third center block with cross-shaped anti-skid portions arranged at a tire face center line of the block units, a first tire shoulder block and a second tire shoulder block which are arranged at the tire shoulder position, and two first transition blocks and two second transition blocks which are arranged at the transition area between the tire face center line and the tire shoulder. The treadpattern blocks are arranged to be polygons. The second center block and the third center block are arranged to be a whole transverse tread pattern block and a whole longitudinal tread pattern block with the left and right ends protruding outwards. The first transition block is in a b shape with the front end being narrow and the rear end being wide. The second transition block is in a quadrilateral shape. The performances of anti-skid, ground holding and traction of the tire are improved, rigidity of the tread pattern blocks is achieved, and off-road performance is guaranteed.

Description

technical field [0001] The present invention relates to a pneumatic tire, and more particularly to a tread pattern structure of a pneumatic tire for mountain bikes. Background technique [0002] The fat bike is a new model extended from mountain bikes. It mainly travels on ice and snow and light off-road roads. Compared with traditional mountain bikes, the road conditions used by this model are relatively flat, and its supporting tires have a larger broken width. Therefore, compared with traditional mountain bikes The carcass of the tire is wider, the shock absorption and cushioning effect are good, and the riding stability is good when used in wild road conditions. However, the road surface in winter is covered with ice and snow. Inadequate traction performance. [0003] Ignoring the impact of materials on tire performance, the following three methods are currently used to improve anti-skid, grip and traction performance: [0004] 1. Set serrated or wavy knife grooves on ...

Problems solved by technology

[0008] Therefore, the above three methods have indeed improved the performance of ice and snow roads to a certain extent, but at the same time they also bring the above-mentioned negative effects, and cannot cope with the ice and snow and light off-road roads that fat cars pass through.
