Michelin 23420 Pilot Sport 4S 265/40R20 104Y XL BSW Summer Performance Tire

The Michelin Pilot Sport 4S is a Max Performance Summer tire engineered in collaboration with the world's most demanding automakers — including Audi, BMW, Mercedes-Benz, and Porsche — incorporating technologies derived directly from the 24 Hours of Le Mans endurance racing program. Designed for sports cars, high-performance sedans, and luxury vehicles, this tire delivers exceptional steering precision, directional stability, and confidence-inspiring grip in both dry and wet conditions.

Key Features:

• Dual-Compound Asymmetric Tread Design: The outer shoulder uses an advanced dry-focused rubber compound for superior dry handling and braking, while the inner shoulder and center ribs feature a silica-infused wet compound for outstanding wet-weather braking performance.
• Adaptable Contact Patch 3.0: Computerized modeling optimizes pressure distribution across the contact patch during cornering, reducing hot spots and promoting even treadwear for extended tire life.
• Hybrid Cord Inner Structure: Steel belts are protected by a spirally wound Aramid and nylon hybrid cord, providing lightweight, full-strength support for improved high-speed handling and stability.
• One-Ply Polyester Cord Casing: Stabilizes the tire structure for a comfortable, responsive ride at all speeds.
• Premium Touch Sidewall Finish: The outer sidewall features a refined velvet-like texture, complemented by a deep rim protector to help guard against light wheel damage.
• Extra Load (XL) Rated: Engineered to handle higher load capacities at elevated inflation pressures, making it well-suited for heavier performance vehicles.
• Black Sidewall (BSW): Clean, classic appearance that complements sport and luxury wheel designs.

The Michelin Pilot Sport 4S is a Max Performance Summer tire and is not recommended for use in near-freezing temperatures, on ice, or in snow. For optimal performance, this tire should be operated in temperatures consistently above freezing. Tires exposed to temperatures at or below 20°F (-7°C) must be allowed to gradually return to at least 40°F (5°C) for a minimum of 24 hours before mounting, inflating, or driving.
