1. Safety performance on wet grounds four wide longitudinal straight groove efficiently drain off water ,improving sideslip performance on wet grounds.
2. Small shoulder circumferfntial longitudinal grooves at both sides and plump little pattern blocks on shoulders bring indeal rigidity and excellent handing.meanwhile,small circumferentia longgitu-dinal grooves enable tires shoulders to diffuse heat quickly,providing higher safety performance.
3. Comfort and quietness small cross-slots at both side of continuous circumferential ribs in the middle simulate the muffler design principle and have strong noise absorption capacity thus ,noise is effectively reduced,and riding comfort is improved.
