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.
