WinterCraft Ice Wi31 Winter

The Kumho WinterCraft Ice Wi31 is a dedicated winter tire built for passenger cars, CUVs, and smaller SUVs facing snow, ice, and slush. It's a studdable design: every size ships with molded stud pockets, so drivers in regions that permit studs can add them for maximum ice bite, while others can run it stud-free for a quieter ride. The Wi31 pairs Wide-Turbine Stud Technology with 3D Honeycomb Siping to multiply biting edges across the tread, and a directional V-shaped tread with wide grooves clears water, slush, and melting snow to help control hydroplaning. A high-dispersion cold-weather compound stays pliable well below freezing rather than hardening up, keeping the tread in contact with the road when temperatures drop. The tire is 3PMSF (Three-Peak Mountain Snowflake) certified, meaning it has passed validated severe-snow traction testing rather than relying on the tread-pattern-only M+S symbol alone. It's sold in a broad size range covering 13- to 19-inch wheels in both T and Q speed ratings. The WinterCraft Ice Wi31+ is the same core winter platform in additional/updated sizes and trim. This is a dedicated cold-weather tire — like all winter tires, its compound is not intended for sustained use once temperatures stay consistently above about 45°F (7°C).
