DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] A tire shoulder structure, see Figure 1 As shown, the tire includes a crown, sidewalls and shoulders. The crown is a circular ring structure that surrounds the tire. The sidewalls are symmetrically provided at both axial ends of the crown. A shoulder with an arc transition is provided between the crown and the sidewalls. The crown, shoulder and sidewalls are integrally formed.

[0029] Multiple groups of central pattern blocks 4 are evenly arranged around the crown, and each group of central pattern blocks 4 includes a first middle pattern block and a second middle pattern block. The first middle pattern block 41 and the second middle pattern block 42 are fan-shaped block structures that are arranged in reverse dislocation. A fine groove 43 is arranged in the middle of the end surface of the first middle pattern block 41 and the second middle pattern block 42, which can effectively disperse the pattern rigidity, improve traction and improve tire durability. Step grooves of the same width are arranged on the periphery of the first middle pattern block 41 and the second middle pattern block 42. The step grooves increase the deformation tolerance of the pattern block end surface in the direction where they are located, and the step grooves increase the strength of the central pattern block.

[0030] Side pattern blocks are arranged uniformly on both sides of the radial direction of the central pattern block group 4, and the side pattern blocks extend from the side of the crown to cover the shoulder to the side of the tire. The same group of central pattern block groups 4 and the corresponding side pattern blocks on both sides have the same inclination direction, and oblique grooves in the same direction are formed between adjacent central pattern block groups 4 and the corresponding side pattern blocks on both sides, which is convenient for discharging sand and stones in the groove.

[0031] Both the center tread block and the side tread blocks are provided with multiple irregular edges. The edges of different directions and shapes can enhance the multi-directional traction of the tread blocks.

[0032] See also Figure 2 , 3 As shown, the side pattern blocks in this embodiment include three types: a first side pattern block 1, a second side pattern block 2, and a third side pattern block 3. The side of the first side pattern block 1 located on the side away from the center line of the tread is the first outer edge 11, the side of the second side pattern block 2 located on the side away from the center line of the tread is the second outer edge 21, and the side of the third side pattern block 3 located on the side away from the center line of the tread is the third outer edge 31; the first outer edge 11, the second outer edge 21, and the third outer edge 31 are at different distances from the center line of the tread, thereby forming different tread widths, and the side pattern blocks of different widths are cross-arranged, thereby improving traction performance. In this embodiment, the first outer edge 11, the second outer edge 21, and the third outer edge 31 are 90 mm, 93 mm, and 94 mm from the center line of the crown, respectively.

[0033] The sides of the first side pattern block 1 and the second side pattern block 2 close to the central pattern block group 4 are both provided with knife grooves 22, and the knife grooves 22 are connected to the middle side to enhance traction, improve rock climbing performance and grip during rock climbing.

[0034] A long groove 32 penetrating through a circumferential side of the middle side is provided on the side of the third side pattern block 3 close to the central pattern block group 4 .

[0035] Step grooves are formed at the edges of the side tread blocks of the crown part. The step grooves increase the deformation capacity of the end faces of the tread blocks. The deformation can generate a greater reaction force. The step grooves can further enhance the traction capability.

[0036] See also Figure 4 As shown, the first side pattern block 1, the second side pattern block 2 and the transition surface of the third side pattern at the shoulder position are all a combination of a plane 6 and a right-angle 5 structure. The straight-edge and right-angle structure can improve the climbing performance and the grip during climbing.
