Track-Focused Design Features:

• Single Compound Technology: Optimized semi-slick compound provides consistent performance and grip throughout the tire's lifespan with shorter warm-up time
• 5.5mm Tread Depth: Molded at 5.5mm (6/32") to reduce tread squirm and maximize contact patch stability for faster lap times
• Kevlar Reinforcement: Sizes 17" and larger feature kevlar lining for enhanced stability, heat resistance, and consistency during demanding track sessions
• Wide Center Ribs: Improves steering precision and response for confident turn-in and mid-corner control
• Large Shoulder Blocks: Increases tire stiffness and traction on curved roads for improved cornering performance
• Optimized Contact Patch: Wider tread footprint delivers maximum stability during high-speed driving

Competition Proven: The AR-1 serves as the control tire for multiple racing championships including BMW 1 Series SuperCup, Civic Challenge, and Classic VW Cup, and has earned podium finishes in open tire series across Time Attack, HPDE, and Circuit Racing events. Designed to handle high-intensity circuits such as Nürburgring and Spa-Francorchamps, this tire has achieved EU tire labelling and Motorsport UK List 1B approval.

Specifications: 100 UTQG treadwear rating, DOT-approved for street legal use. Available in sizes from 12" to 21" rim diameters. Recommended for 90% track / 10% road use. Note that as a competition tire, street mileage will be significantly reduced compared to standard road tires, but performance is true race-car quality.

Break-In Recommendation: For optimal performance and tire life, an initial heat cycle (scrubbing in) is recommended before pushing the tires to their limits on track.
