The deep pattern design of three large blocks in the horizontal direction has excellent grip, traction, bite resistance and puncture resistance on non-paved roads such as mines. The large transverse pattern block in the middle is connected by stiffeners to prevent groove cracking. The flared open transverse groove on the shoulder has reduction and heat dissipation effects. The hollow-shaped design with a variable depth in the middle is 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 surface of the pattern is filled with a regular size lattice pattern, and the hemp surface effect is rough and beautiful.
