Bridgestone 004853 Potenza S001 RFT 225/40R18 92Y XL Run-Flat Ultra High Performance Summer Tire

The Bridgestone Potenza S001 RFT is an ultra-high performance summer run-flat tire engineered to meet the exacting standards of the world's most prestigious automakers. Offered as original equipment on select BMW vehicles and premium performance sedans, the Potenza S001 RFT delivers confident handling and grip in both dry and wet conditions — all while incorporating Bridgestone's proven run-flat technology.

Tread Design & Wet/Dry Performance

• Asymmetric tread pattern — Large outer shoulder tread blocks maximize dry-road grip and cornering stability, while smaller inner shoulder elements improve wet-weather traction and hydroplaning resistance.
• Solid circumferential center rib — Maintains continuous road contact to sharpen steering response and improve braking performance on dry surfaces.
• Three wide circumferential grooves — Efficiently evacuate water from the contact patch, delivering strong hydroplaning resistance in wet conditions.
• Slanted-slug shoulder sipes — Combined with a high-performance summer compound, these sipes enhance grip and overall surface contact at speed.

Run-Flat Technology

• Reinforced sidewall construction — Heat-resistant, thickened sidewalls support the full weight of the vehicle and passengers even after a complete loss of air pressure.
• Extended mobility — In the event of a puncture or blowout, the tire provides up to 50 miles of continued driving at speeds up to 50 mph, allowing time to safely reach a service facility.

High-Speed Durability & Comfort

• Twin steel belts spirally wrapped with nylon cord — Reinforce the internal structure to resist deformation under high-speed driving loads, supporting the tire's Y-rated speed capability.
• Heat-resistant compound — Prevents heat buildup across the tread and sidewall during sustained high-speed use.
• Vibration-damping construction — Multiple heat-resistant technologies work together to minimize road vibrations transmitted to the cabin, enhancing ride comfort without compromising performance.

The Bridgestone Potenza S001 RFT in 225/40R18 92Y XL is the ideal choice for performance-oriented drivers who demand responsive handling, all-weather summer traction, and the added safety net of run-flat capability.
