Michelin Pilot Sport 4 ZP – 255/35 ZR18 94Y XL TL is an Ultra High Performance summer run-flat tyre designed for sporty passenger cars that require high-speed stability combined with extended mobility after a puncture. It utilises Michelin’s Zero Pressure (ZP) technology, allowing continued driving for a limited distance at reduced speed in the event of air loss. The advanced asymmetric tread pattern incorporates wide circumferential grooves for efficient water evacuation and reliable wet grip. Michelin’s Dynamic Response belt technology enhances steering precision and maintains consistent road contact during high-speed driving. Reinforced outer shoulder blocks improve cornering stability, while the XL construction supports load capacity and structural rigidity. With a Y speed rating, the Pilot Sport 4 ZP delivers responsive handling, confident braking, and safety-focused performance for premium and performance vehicles.
