The four wide longitudinal drainage grooves provide excellent wetland performance of the tire,which effectively prevent the side sliding The coupling design with the crosswise arc grooves and fine arc slots effectively damaged the water film in the wet road, which provide better grasp force in the wetland. The 3D slots design increased the braking and grounding area to provide bigger traction force. Meantime it effectively increased the heat radiation area and improved the endurance performance of the tire.
