Kumho WinterCraft Ice WI31 Studdable Winter Tire

The Kumho WinterCraft Ice WI31 is a studdable winter radial tire engineered for passenger cars, CUVs, and SUVs that demand reliable cold-weather performance. Carrying the Three-Peak Mountain Snowflake (3PMSF) certification, the WI31 is purpose-built to meet severe winter service standards — delivering confident traction, responsive handling, and shorter stopping distances on ice, packed snow, and slush.

Key Features:

• Wide Turbine Stud Design: Low-profile wide turbine studs provide excellent snow and ice clearance while reducing road noise for a more comfortable winter driving experience
• Optimized Stud Placement: Strategically arranged studs — utilizing up to twenty rows versus the industry-standard fourteen — maximize braking and acceleration performance on icy surfaces for enhanced safety in severe winter conditions
• High-Dispersion Winter Compound: Specially engineered rubber compound maintains flexibility in extreme cold, sustaining traction and grip well below freezing; this tire is designed for use when temperatures consistently fall below 45°F
• 3D Honeycomb Sipe Technology: High-density multi-directional sipe pattern stabilizes tread blocks, multiplies biting edges, and improves handling precision and braking performance on snow and ice
• Directional Tread Pattern: Optimized V-shaped directional grooves efficiently evacuate water, slush, and melting snow to reduce hydroplaning risk and boost steering responsiveness
• Reinforced Shoulder Blocks: Aggressive shoulder tread block placement increases cornering grip, road contact, and overall driving stability throughout winter conditions
• Studdable Construction: Pre-drilled for optional metal studs where permitted by law, offering maximum versatility for drivers facing the most severe winter climates
• 3PMSF Certified: Meets the industry standard for severe snow service, confirming the WI31's readiness for genuine winter driving conditions
