A large pattern design with higher pattern saturation and an anti-puncture step design for the bottom of the groove. The use of high-strength new structural steel wire provides stronger load capacity, reducing the deformation of heavy tire loads. Anew formula for low heat generation, high cutting resistance and wear resistance in mining prolongs the serice life. The bead which is close to the rim contributes small deformation, low heat genera-tion and long serice life under heavy load.
