Pneumatic tyre tread pattern structure for cruise bike on beach

Abstract

The invention discloses a pneumatic tyre tread pattern structure for a cruise bike on the beach. A tyre comprises a tread part, a pair of bead parts and a pair of edge parts, wherein the tread part is in direct contact with the ground; the bead parts are assembled with rims in a matching manner; the edge parts are connected with the tread part and the bead parts; waterproof wires are arranged at the edge parts on two sides and at the positions close to the bead parts; the space between the waterproof wires at the edge parts on two sides and the tread part is uniformly divided into two center areas, boundary areas and transition areas; tread patterns are formed in such a way that a plurality of pattern units are radially distributed on a tread; and each pattern unit comprises at least two arc-shaped main grooves crossing the center areas, the boundary areas and the transition areas, and longitudinal groove groups distributed in the center areas, the boundary areas and the transition areas. The cross section outline of an inflated tyre is similar to an air balloon, so that the driving stability and comfort are increased, the abrasion resistance of the tyre on a hard paving road is ensured, and the pull-out performance and the traction performance of the tyre on the soft beach are improved.

Description

technical field [0001] The invention relates to a pneumatic tire, in particular to a tread pattern structure of a bicycle pneumatic tire used for leisure on the beach and its vicinity. Background technique [0002] With the widespread popularity of bicycle sports, more and more consumers ride bicycles to the beach and its surrounding areas for tourism, leisure and fitness. Since the road conditions it passes are mainly soft beaches and hard paved roads with fine sand on the surface near the beach, the section width of the tires used on this type of bicycle is generally 2.0~2.5 inches, and the inflation pressure is lower to obtain more Large ground area. [0003] Such as figure 1 In the current common bicycle pneumatic tire section structure 1' shown, the tread pattern extension width is maintained within the expanded width OW' of the tread portion 10', and transitions to the bead portions 20' on both sides through the shoulder 11' . Beach leisure bicycle tires have low i...

AI Technical Summary

Problems solved by technology

Beach leisure bicycle tires have low inflation pressure and require a larger ground contact area, but the current tire tread width has a specific ground contact range, and the current bicycle tire bead is basically designed with a smooth surface except for the text, which is suitable for passing on soft sand bad sex

[0004] Therefore, the current conventionally designed bicycle tires cannot meet the performance requirements of beach leisure bicycles. It is necessary to study and improve the design of tire section profile and tire pattern, in order to achieve the purpose of enhancing the passability of crossing the beach and improving the comfort and stability of the paved road.
