[0034] The first transverse groove 4, the second transverse groove 5, and the third transverse groove 6 each comprise at least one V-shaped groove and are arranged in plurality along the direction of movement of the tire, and are respectively arranged transversely through the first central longitudinal pattern rib 1, the second central longitudinal pattern rib 2, and the third central longitudinal pattern rib 3;
[0035] Cutting angles are provided at the outer end surfaces of both sides of the first middle longitudinal pattern rib 1, the second middle longitudinal pattern rib 2, and the third middle longitudinal pattern rib 3;
[0036] The first central longitudinal pattern rib 1, the second central longitudinal pattern rib 2 and the third central longitudinal pattern rib 3 are respectively separated into a first longitudinal pattern block 1-1, a second longitudinal pattern block 2-1 and a third longitudinal pattern block 3-1 of inconsistent shapes and sizes by longitudinal grooves, cut corners and a plurality of first transverse grooves 4, second transverse grooves 5 and third transverse grooves 6.
[0037] Specifically, such as Figure 1 As shown, the first central longitudinal pattern rib 1, the second central longitudinal pattern rib 2, and the third central longitudinal pattern rib 3 form first longitudinal pattern blocks 1-1, second longitudinal pattern blocks 2-1, and third longitudinal pattern blocks 3-1 of different sizes and shapes under the separation of the first transverse groove 4, the second transverse groove 5, the third transverse groove 6, the longitudinal grooves, and the cut angle. The size and shape changes here may be caused by the different structural shapes of the first transverse groove 4, the second transverse groove 5, and the third transverse groove 6 themselves, or by the different widths of the longitudinal grooves and the different structural shapes of the cut angles, or by the above-mentioned different combinations. Those skilled in the art have reason to refer to the above-mentioned different combinations of related settings to form first longitudinal pattern blocks 1-1, second longitudinal pattern blocks 2-1, and third longitudinal pattern blocks 3-1 of different sizes and shapes.
