Introduction：

Tire shoulder disigned with bigger blocky pattern to increase the maneuverability of the tire; the tread blocks of tire shoulder increased week to rill and horizontal steel channel to improve its thermal performance, as well as to increase the shoulder rib tread design to improve the abnormal pattern of anti-wear properties; central pattern forms a straight tread pattern is conducive to vehicles traveling straightly; increased by a small ditch steel groove pattern designed between the tread center and shoulder blocks to reduce tire noise; the steel tread grooves on the pattern block enhance shock absorption performance, and improve tire grip, comfort and handling, while reducing its noise.
