Graspic DS-2 tires represent the 2nd generation of Dunlop Digi-tire Studless Ice and Snow winter tires designed to deliver traction for drivers who want enhanced control in snow and on ice. The DS-2 studless winter tires feature a glass fiber-reinforced, high silica tread compound molded into a heavily zigzag siped, low void, symmetric tread design with a wide, central snow pillar groove to provide excellent traction on ice and in snow.
