Bridgestone Potenza The Bridgestone POTENZA RE050 Run-Flat

Run Flat Tires Front - Rear - 225/45R17

The Bridgestone POTENZA RE050 Run-Flat is ultimate luxury tyre in the POTENZA range, with high speed performance, great handling and stability. It is fitted as original equipment on leading super cars including Ferrari, Porsche, Aston Martin, BMW, Audi, Lexus and Mercedes Benz. Additional about Run-Flat Technology: Conventional tires use pressurized air to support the weight of the vehicle. However, when the tire is punctured, air escapes and the weight of the vehicle is no longer supported. This creates a flat tire. When a run-flat tire is punctured, it loses air, but it continues to support the vehicle’s weight using the reinforced sidewalls. The Bridgestone group’s run-flat tires give drivers peace of mind. Unlike conventional tires which need to be changed or repaired immediately after a puncture, run-flat tires can safely drive on for up to 50 miles (80 kilometers) at 50 mph (80 km/h).
