Bridgestone 004855 Potenza S-001 RFT 225/35R19 88Y XL Run-Flat Summer Performance Tire

The Bridgestone Potenza S-001 Run-Flat Tire (RFT) is a max-performance summer tire engineered for ultra-high-performance sports cars and prestige sedans. Developed to meet the exacting OEM standards of leading automakers, the Potenza S-001 RFT delivers confident handling in both dry and wet conditions while incorporating Bridgestone's self-supporting run-flat technology for added peace of mind.

Run-Flat Technology:

• Bridgestone Side Support RFT — Heat-resistant, reinforced sidewalls are designed to temporarily bear the vehicle's weight after a complete loss of air pressure
• Allows continued driving for up to 50 miles at speeds up to 50 mph after a puncture or total pressure loss, providing time to safely reach a service facility
• Eliminates the immediate need to change a tire roadside

Tread Design & Performance:

• Asymmetric tread pattern — Large outboard shoulder blocks and interlocking tread elements enhance dry-road steering response, high-speed stability, and cornering precision
• Solid central circumferential rib — Promotes straight-line stability and responsive steering feel
• Wide circumferential grooves combined with high-angle lateral grooves channel water away from the contact patch, improving wet-weather grip and hydroplaning resistance
• Inner shoulder comprised of smaller, more numerous tread elements to improve wet traction without sacrificing dry performance

Construction & Durability:

• Lightweight belt package featuring twin steel belts reinforced with spirally wrapped aramid/nylon cord — reduces rolling resistance and enhances high-speed durability
• Special heat-resistant rubber compound throughout the sidewall and tread resists thermal build-up during extended high-performance use

Important Notes:

• Summer-only tire — not intended for use in near-freezing temperatures, snow, or ice
• Bridgestone recommends installing Potenza S-001 RFT tires in sets of four only
• Must not be mixed with other Potenza RFT models (RE050 RFT, RE050A RFT, RE050A I RFT, or RE050A II RFT)

The Bridgestone Potenza S-001 RFT combines ultra-high-performance summer grip with the security of run-flat capability, making it an ideal choice for performance-oriented drivers who refuse to compromise on either speed or safety.
