There are a total of 4 large pattern designs in the horizontal direction, which are arranged in a "Λ" shape as a whole, with directional patterns, providing strong driving force and adapting to mixed road surfaces. The surface is made of turning decorative steel sheet,which is rotationally symmetrical, harmonious and beautiful. The bottom of the ditch adopts a stone removal structure to reduce stone clamping and enhance the impact resistance and puncture resistance of the tire. The center of the pattern block and the circumference of the two shoulders are connected by stiffeners, and the transverse pattern blocks are also connected by stiffeners to prevent groove cracking. The open shoulder design improves the heat dissipation performance of the tire and improves the durability.
