Introduction：

Big blocks connected with reinforceed bar and narrow and thick groove in the tread provides good operation in the curve and good adhesion in the snow road in the condition of low temperature. Thanks to narrow groove pattern with shallow and deep interval and straight block pattern in the middle of the tread, good grip performance and good straight running in the low temperature. Zigzag groove provides good traction performance in the snow and mud, and low noise emission and comfortable operation. Block design in the shoulder and middle of the tread, with thick and narrow groove pattern with shallow and deep interval. Provides good operation off the road and down the rigidity of the tread block in the low
