1.The four widely longitudinal grooves greatly enhance the drainage of tyres on wet land.pervents the tire side-slip.
2.The entire running surface is covered with vertical and horizontal thickness of the connecting groove combinations of vertical drainage destruction of the rain ater film.
3.Double arc patterns not only eliminate the the noise validly reduce the rolling resistance.
4.Excellent step width and optimized arrange of the step has validly but reduce the tires deep resonance noise when the car is running
5.The longitudinalfurrow of the shoulder's circumference makes the tire heat concentrated shoulder fast heat dissipation which improved the safety performance of the tire.
