The Potenza RE050 RFT is Bridgestones Max Performance Summer run-flat tire developed exclusively for specific Audi, BMW, Maserati and Mercedes-Benz vehicles. The tire is designed to provide temporary extended mobility for a distance of 80 kilometers at up to 80 kph after a puncture has allowed complete air pressure loss.
The Potenza RE050 RFT features a high-grip tread compound molded into a directional tread design. A continuous center rib, large tread blocks and stable shoulder elements provide responsive handling, high-speed stability and traction on dry roads, while circumferential and lateral tread grooves are aimed to pump water out from under the tire's footprint to minimize hydroplaning and aid wet traction.
The tires internal structure includes twin steel belts reinforced by spiral-wrapped nylon to stabilize the tread area and enhance handling, high-speed capability and ride quality. The structure of the Potenza RE050 RFT also features Bridgestone Side Support Run-Flat technology reinforced sidewalls to support the vehicle after a puncture caused a loss of air pressure.
