Wide main trench design:Improve drainage performance and improve wetland control performance. Semi-closed cross ditch design:Reduce air flow in longitudinal and transverse trenches and reduce noise. Steel groove design:Cut the water film, improve the tire wet performance. Transverse groove chamfer design:Reduce the noise of the pattern block hitting the ground,and increase the ground area when starting and braking,driving quiet and safe. Shoulder slope design:As the tread wears, the actual ground width increases, ensuring a full life cycle grip. Spoiler design:Disrupts the air flow in the vertical grooves during driving to reduce pumping noise.
