The Graspic DS-3 represents the third generation of Dunlop Digi-tire Studless Ice and Snow winter tires developed for the drivers of coupes and sedans, as well as family minivans and crossover utility vehicles. Graspic DS-3 tires use Dunlop's Digital Rolling Simulation II technology (computer-enhanced design) and premium tread compounding to deliver wintertime traction in snow and on ice. Graspic DS-3 studless winter / snow tires feature a silica-based, glass fiber-reinforced tread compound molded into a symmetric independent block tread design to provide grip in snow and on ice without resorting to traditional metal studs. High-density Miura-shaped sipes (featuring a three-dimensional interlocking zigzag design) help stiffen the tread blocks to promote steering feel and even tread wear. The Graspic DS-3's Digital Rolling Simulation II technology helps optimize tread pattern stiffness to enhance footprint pressure distribution for improved grip and treadlife. Graspic DS-3 winter tires meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol.
