- More Drainage, Less Noise. Five-pattern-block design has been engineered to expel water and reduce noise under a variety of road and terrain conditions. - High Stability Tread Corners. The special cutting corner on all borders of the groove pattern makes it more dimensional, more 'stereoscopic' and more effective at promoting driving stability and comfort. - Zigzag Middle Block. The zigzag pattern design of the middle tread element reduces noise while the sloped corner repels rocks and improves earth-grasping performance. - Special Shoulder Shape. The bench-shaped shoulder design provides excellent earth-grasping action for stable high-speed turns under dry and wet road conditions.
