Four wide and deep main ditches:Excellent drainage to enhance wetland grip performance. Improve drainage:Mud removal performance, improving wetland grip performance. Block the propagation of noise from longitudinal groove pump suction to the outside:Reduce the noise from the outside and in the ear of the car, and ensure the stability of driving and steering by connecting the patterned ribs. Effectively dispersing tire noise:Achieve mute effect. Shoulder sulcus dislocation:Generating interference effects, beneficial for reducing noise. Interconnection between steel sheets and grooves:reduce the noise. Enhancing wetland grip:Change the frequency of flower blocks hitting the ground to reduce noise. As the tread wears, the actual grounding width increases:Ensuring ground grip performance throughout the entire lifecycle.
