Performance Highlights

The AS‑2+ XL combines the best of both worlds: the safety of a runflat tyre with the performance characteristics expected from a summer racing tyre. Its symmetric tread layout ensures consistent handling across all four wheels, while the deep circumferential grooves provide superior hydroplaning resistance at high speeds.

Drivers will notice:

• Responsive Steering: The tyre’s low‑profile sidewalls deliver precise steering feedback and minimal body roll during cornering.
• Comfort & Quietness: Advanced tread design reduces road noise, offering a smooth ride even on rough surfaces.
• Long Wear Life: The reinforced carcass and high‑quality compound reduce wear rates, keeping the tyre’s performance consistent over thousands of kilometres.

Ideal Vehicle Applications

The AS‑2+ XL is engineered for a wide range of passenger cars and light SUVs that require high speed capability and runflat safety. Common applications include:

• SUVs such as the Audi Q5/Q7, Jaguar F-Type, and Maserati Quattroporte.
• Luxury sedans like the Audi A6/A8 and Mercedes‑E-Class.
• Performance coupes and convertibles that benefit from reduced unsprung weight.

Installation & Maintenance Tips

1. Proper Inflation: Maintain the recommended pressure of 2.5–3.0 bar (36–44 psi) to ensure optimal tread contact and longevity.
2. Tread Depth Monitoring: Check for minimum tread depth of 1.6 mm; replace when it reaches this limit to preserve wet‑grip performance.
3. Balanced Load Distribution: Use a calibrated tyre balance machine to avoid uneven wear and vibration.
4. Runflat Awareness: After a puncture, drive no more than 80 m at speeds below 80 km/h before seeking professional repair or replacement.
