Michelin 01806 Pilot Super Sport 255/40ZR18 (99Y) XL Max Performance Summer Tire

The Michelin Pilot Super Sport 255/40ZR18 (99Y) XL is Michelin's flagship max-performance summer tire, born directly from endurance racing heritage. Engineered for drivers who demand the absolute best in dry and wet grip, progressive handling, and long-lasting tread life, the Pilot Super Sport raises the bar for ultra-high-performance street tires. It was originally introduced as original equipment on some of the world's most exclusive performance vehicles, including the limited-edition Ferrari 599 GTO.

Key Features:

• Bi-Compound Tread Technology: The asymmetric tread design uses a Le Mans-inspired dry compound on the outer shoulder for superior cornering and braking, while the inner tread and notched center ribs use a wet-oriented elastomer compound engineered for wet traction and high-speed stability.
• Twaron Belt Package: Twin steel belts are reinforced by spirally wound Twaron — a lightweight, high-strength polyamide cord — positioned above the steel belts to enhance high-speed handling, tread wear, and durability.
• Variable Contact Patch 2.0: Optimized contact patch geometry promotes long, even treadwear across the full width of the tire, extending usable tread life.
• Lightweight Construction: Weight savings of up to 10% compared to tires of similar dimensions reduces unsprung weight for improved steering response and handling feel.
• Polyester Body Ply: A single-ply polyester carcass promotes a comfortable, compliant ride without sacrificing responsiveness.
• XL (Extra Load) Rated: Reinforced construction supports higher load capacities at elevated inflation pressures.
• Asymmetric Design: Dedicated inner and outer tread zones are optimized independently for wet and dry performance respectively.
• OE Fitment Heritage: Designed as original equipment on the Ferrari 599 GTO and selected as OE on other world-class performance vehicles.
