Bridgestone 013746 Potenza S-001L Run-Flat Tire 275/35R21 99Y

The Bridgestone Potenza S-001L Run-Flat (RFT) is a Max Performance Summer tire developed as Original Equipment (OE) for premium high-performance sports cars, coupes, and sedans. Engineered to deliver exceptional dry and wet grip, confident cornering, and enhanced steering response, the Potenza S-001L RFT is purpose-built for drivers who demand the highest levels of performance from their vehicle.

Bridgestone's Run-Flat Technology (RFT) features reinforced sidewalls that support the vehicle's weight even after a complete loss of tire pressure, allowing continued driving for a limited distance so you can safely reach a service location without changing a tire on the roadside.

Key Features:

• Advanced asymmetric tread pattern — optimizes contact patch for both dry grip and wet evacuation
• Large outside shoulder blocks — deliver confident, stable cornering performance
• Continuous center rib — provides enhanced steering response and straight-line stability
• Wide circumferential grooves — channel water away from the footprint to reduce hydroplaning risk
• High-angle lug grooves — improve wet braking performance and water evacuation
• Run-Flat sidewall construction — supports vehicle load after pressure loss for extended mobility
• OE fitment — developed specifically as original equipment for premium performance vehicles
