A high-end tire designed to handle the worst winter weathers. Goodyear developed the Ultra Grip Ice winter tire for passenger sedans, crossovers, vans and SUVs, features the ''Winter Reactive Technology'' which is indeed one of the best technology on the market. This advanced technology provides excellent grip in deep snow and excellent traction on ice, for a smooth ride and a safe driving. The Goodyear Ultra Grip Ice also has a significant advantage to stop faster on ice than its main competitor and offers extended durability and an excellent ride comfort. The high performance of the Goodyear Ultra Grip Ice in grip and traction in winter conditions with ice, snow, slush and cold weather is mainly attributable to the following: first, the rubber compound is specifically designed for winter and ice, and then its 3D interlocking shoulder sipes guarantee a secure grip and perfect stability when cornering. In addition, the GoodYear Ultragrip Ice has a directional ''tread to tread'' contact design maximizing the impact on adherence by providing better slush and snow drainage which in turn increases maneuverability and resistance to aquaplaning. The two-dimensional tread center rib sipes provide greater acceleration and braking force on snow and ice.
