Kenda VEZDA UHP A/S KR400 Ultra-High Performance All-Season Tire

The Kenda Vezda UHP A/S (KR400) is an ultra-high performance all-season passenger tire engineered for sports cars, sedans, and coupes that demand year-round versatility without sacrificing handling or ride quality. Developed at the Kenda American Technical Center in Akron, Ohio to meet U.S. performance expectations, the KR400 bridges the gap between summer tire responsiveness and all-season confidence — delivering sharp, precise control in dry, wet, and light snow conditions.

Key Features & Technology:

• Advanced Silica Compound: Blends summer tire responsiveness with cold-weather flexibility, enhancing grip and traction across all weather conditions while promoting even, long-lasting treadwear
• Five-Rib Asymmetric Tread Design: An optimized footprint features a low void ratio toward the shoulder for dry-weather cornering grip and a high void ratio toward the inboard side for improved wet-road traction and steering response
• 3D Siping Technology: Precision-cut sipes create additional biting edges for enhanced traction in wet and light winter conditions while maintaining tread block stability and wear resistance
• Four Wide Circumferential Grooves: Efficiently evacuate water from the contact patch for strong wet traction and outstanding hydroplaning resistance
• Built-In Rim Flange Protector: Guards the wheel and sidewall against curb damage and everyday road impacts
• Computer-Tuned Tread Pitch: Optimized pitch sequencing minimizes road noise for a refined, comfortable driving experience

Ratings & Certifications: The KR400 carries an M+S rating for all-season capability and earns a UTQG rating of 500 AA A — reflecting a strong balance of treadwear durability, wet traction, and temperature resistance. Speed ratings across the lineup reach up to Y (186 mph), making the KR400 a genuine ultra-high performance option for enthusiast drivers.

Warranty Coverage: Backed by a 50,000-mile limited treadwear warranty on standard fitments (25,000 miles for staggered front/rear applications), the Vezda UHP A/S KR400 delivers long-term confidence and peace of mind for everyday performance driving.
