Michelin 15657 Pilot Sport 4S 295/30ZR21 102Y Ultra-High Performance Summer Tire

The Michelin Pilot Sport 4S (MPN: 15657) is a 295/30ZR21 102Y ultra-high performance summer tire engineered for sports cars and high-performance sedans. Delivering unparalleled driving pleasure, the Pilot Sport 4S combines exceptional steering precision with directional stability for a truly exhilarating driving experience.

At the heart of the Pilot Sport 4S is Michelin's advanced bi-compound tread technology, which optimizes performance across both dry and wet surfaces. The outer tread zone features a new hybrid compound formulated for maximum grip on dry pavement, while the inner tread zone incorporates a silica-enhanced compound with functional elastomers to deliver consistent traction in wet conditions — a pairing of characteristics that traditionally conflict in the super-sport tire segment.

Key Features:

• Bi-Compound Tread Technology: Dual tread compounds simultaneously optimize dry and wet grip performance
• Exceptional Braking: Outstanding stopping distances on both dry and wet road surfaces
• Optimized Tread Footprint: Engineered contact patch grips the road confidently even in extreme driving situations
• Directional Stability: Precise steering response and high-speed stability for spirited driving
• Size: 295/30ZR21 with 102Y service description — XL load rating for demanding high-performance applications

The Michelin Pilot Sport 4S is the tire of choice for OEM fitment on some of the world's most demanding production sports cars, and is equally at home on the street as it is pushed to its limits on a closed circuit. Its UTQG rating of 300AA reflects its focus on maximum performance grip and thermal stability.
