Hankook Ventus V4 ES H105 Tire  - 215/55R17 94Z SL The Ventus V4 ES molds an ultra high performance all-season tread compound into a directional design featuring a continuous center rib flanked by stable independent intermediate and shoulder tread blocks to enhance dry traction. Wide circumferential main grooves and multiple lateral side slots create waterways that aid water drainage to minimize hydroplaning and enhance wet traction. Sipes in each tread block increase the number of biting edges to reinforce winter traction without abandoning wet and dry handling.
