Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments (for example, simply changing the shape of the pattern blocks and the arrangement order of the pattern blocks, the gap between the pattern blocks, etc.) obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

The tire structure is comprised of tread, shoulders, sidewalls, toe caps, carcass, belts, innerliner, and other components that are joined to one another, with a tire pattern attached to the tread. The utility model discloses a mould mainly used production possess the tire of this decorative pattern.

Referring to fig. 1-5, the tread of the tire of the present invention is composed of a first tread block 2, a second tread block 3, a third tread block 4 and a fourth tread block 5, and all tread blocks are arranged in a three-dimensional manner with a large bottom and a small top.

The first pattern blocks 2 are of different right and left sizes and are of an angle shape, comprise a plurality of grooves and are symmetrically arranged up and down by taking the center of the tread as an axis; a second pattern block 3 with one end in a quadrangular pyramid shape and the other end in a curved surface is arranged on the shorter side of the first pattern block 2, and grooves are arranged in the second pattern block 3 and are arranged up and down symmetrically by taking the center of the tread as an axis; and a third pattern block 4 with an inner groove and shaped like a Chinese character 'hui' is arranged on one side of the curved surface of the second pattern block 3 and the edge of the tread, and a fourth pattern block 5 with an inner groove and shaped like a Chinese character 'hui' is arranged at the position symmetrical to the third pattern block.

The center of the tread is arranged up and down in an axisymmetric way: one of the first blocks 2 is disposed on the tread with the center of the tread as an axis, and the other of the first blocks is an axisymmetric pattern of the first blocks 2, is disposed above or below the first blocks 2, and is sequentially arranged on the tread.
