Bridgestone 004851 Potenza S001 RFT 225/45R19 92W Run-Flat Summer Performance Tire

The Bridgestone Potenza S001 RFT (Run-Flat Tire) is a max performance summer tire engineered to meet the exacting standards of the world's most prestigious automakers. Chosen as original equipment by manufacturers including Ferrari, Aston Martin, and Lexus, the Potenza S001 delivers confident, precise performance in both dry and wet conditions — without compromise.

This tire features Bridgestone's self-supporting run-flat technology, allowing it to continue supporting the vehicle's weight even after a complete loss of air pressure. In the event of a puncture, the reinforced sidewall construction enables continued driving for up to 50 miles at speeds up to 50 mph, providing the peace of mind to safely reach the nearest service location.

Key Features:

• Asymmetric Tread Design — Large outboard shoulder blocks and interlocking tread elements enhance dry-road grip, steering response, and cornering precision, while the inner shoulder's finer tread elements improve wet-weather traction.
• Circumferential Grooves — Three wide circumferential grooves efficiently channel water away from the contact patch, delivering outstanding hydroplaning resistance and wet-road safety.
• Reinforced Run-Flat Sidewall — Constructed from heat-resistant rubber compounds, the thickened sidewall supports the vehicle's load at zero air pressure, reducing the risk of being stranded roadside.
• Spirally Wrapped Twin Belts — Improve structural rigidity, reduce rolling resistance, and contribute to a smoother, more comfortable ride.
• Heat-Resistant Technologies — Multiple heat management features minimize road vibration transmitted to the cabin, maintaining ride comfort even under demanding high-speed conditions.
• Summer Performance Compound — Optimized for use in warm, dry, and wet conditions; not intended for use in near-freezing temperatures, snow, or ice.

The Potenza S001 RFT in size 225/45R19 92W carries a load index of 92 (1,389 lbs max load) and a W speed rating (up to 168 mph). With a UTQG rating of 280AA and a tread depth of 9/32", this tire balances longevity with the high-performance handling characteristics demanded by sports sedans and coupes.
