Kumho Wintercraft SUV WS71 Studless Winter Tire

The Kumho Wintercraft SUV WS71 is a studless winter tire purpose-built for SUVs and crossovers (CUVs), engineered to deliver confident, safe performance across the full range of winter conditions — snow, ice, slush, and wet roads. Combining an advanced asymmetric tread design with a specially formulated winter rubber compound, the WS71 keeps drivers in control when conditions are at their most demanding.

Advanced Tread Technology:

• Asymmetric Tread Pattern: Specifically designed for the demands of SUVs and CUVs, with distinct inner and outer tread zones that optimize handling stability and traction on snow-covered and icy roads
• 3D Siping with Reinforced Tread Blocks: High-density 3D sipes multiply biting edges for enhanced grip on ice and packed snow, while stiffened shoulder blocks maintain braking performance and cornering stability
• Connected Circumferential Grooves: Continuous drainage channels efficiently evacuate water, slush, and snow from the contact patch, reducing hydroplaning risk and sustaining grip on wet winter roads
• Zigzag Lateral Groove Design: Strategically angled lateral grooves maximize snow traction through enhanced snow-on-snow biting action
• Silica Winter Compound: A specially engineered silica-infused rubber formulation maintains elasticity at sub-freezing temperatures, ensuring consistent contact, grip, and shorter braking distances in extreme cold
• Advanced Bead Technology: Optimized bead construction enhances structural durability, high-speed stability, and a secure fit on the wheel rim

Performance Benefits:

• Confident braking and acceleration on icy and snow-covered surfaces
• Precise, responsive steering in cold and wintry conditions
• Effective hydroplaning resistance on wet winter roads
• Quiet, comfortable ride — optimized tread geometry minimizes road noise on long winter journeys
• Non-directional asymmetric design supports free rotation for even tread wear and extended tire life
• Hourglass-shaped tread wear indicators on shoulder blocks provide a clear, easy-to-read signal of remaining tread life and help identify uneven wear patterns early

The Wintercraft SUV WS71 carries the Three-Peak Mountain Snowflake (3PMSF) rating, confirming it meets the industry standard for severe snow service performance. As a dedicated winter tire, it is optimized for use in temperatures consistently below 45°F — for best results and longevity, it should be used seasonally and swapped for all-season or summer tires when cold weather ends.

Kumho Tire has been producing quality tires since 1960 and is recognized as one of South Korea's leading tire manufacturers. The Wintercraft SUV WS71 reflects that legacy — delivering premium winter performance at exceptional value for SUV and CUV owners who demand dependable cold-weather safety without compromise.
