Nankang AS-1On the outside tread, tread shoulder uses high-stiffness curved pattern design to increase the cornering force and enhance the steering ability. In addition, to get the better drainage effectiveness, two straight broad grooves have been used in the design, as well as the sipe bars adding in the middle groove have been used to accumulate the water for better drainage efficiency and driving safety on the wet ground.
On the inside tread, the evenly thin sipe design can reduce the road impact and enhance driving comfort. Besides, unique straight groove design adding on the tread shoulder not only normalizes the whole tread stiffness and tread contact patch, but also prevents from irregular wear. Unique silica formula on the tread can not only increase the grip on wet ground, but also reduce rolling resistance and even fuel consumption. Prices
