Nankang JD422 AR-1 175/50R13 72V Track Performance Tire

The Nankang AR-1 (JD422) is a high-performance, DOT-legal track tire engineered for drivers who demand the fastest lap times. Designed with a 90% track / 10% road focus, the AR-1 bridges the gap between a dedicated race slick and a street-legal performance tire, making it the ideal choice for time attack, HPDE events, and circuit racing.

Built with a unique semi-slick compound, the AR-1 delivers shorter tire warm-up times, allowing drivers to reach peak grip levels faster on track. With a uniform 5.5mm tread depth and a single compound option across the entire lineup, performance remains consistent and predictable throughout the tire's service life. Sizes 17 inches and above feature an integrated Kevlar lining for enhanced structural stability and heat resistance during high-intensity sessions.

Key Features:

• 100 Treadwear (UTQG 100) — DOT-compliant for street and track use
• Semi-slick compound — reduces warm-up time for immediate grip on circuit entry
• 5.5mm tread depth — minimizes tread squirm and maximizes contact patch rigidity
• Kevlar lining (17" and above) — improves stability and consistency at high speeds
• Special inner angled tread pattern — channels water efficiently for improved wet-weather handling
• Bevel pattern design — increases overall tire stiffness for sharper response
• Wide center ribs — enhance steering precision and on-center feel
• Large shoulder blocks — maximize traction and stiffness through corners
• Optimized contact patch — delivers best-in-class stability at high speeds
• Motorsport UK List 1B approved and EU tire labeled for road use
• Control tire for BMW 1 Series SuperCup, Civic Challenge, Classic VW Cup, and more

Whether you're chasing podiums in a sanctioned race series or shaving seconds off your personal best on a track day, the AR-1 delivers race-level performance in a street-legal package.
