The design of three straight grooves + edge steel sheets can not only provide strong driving force, but also have the performance of fuel saving and consumption reduction. Higher pattern saturation and super wear-resistant tread formula to increase the ground contact area and improve excellent wear performance. Closed shoulder design to improve shoulder rigidity and avoid abnormal shoulder wear. Strengthened toe material design to provide strong load resistance and flexure burn resistance. The design of the stone strip at the bottom of the groove can reduce the stone clamping and protect the base of the tread.
