The Potenza S001 RFT (Run-Flat Tire) is Bridgestone’s Max Performance Summer self-supporting run-flat tire developed as Original Equipment exclusively for BMW 3 Series sedans beginning with 2012 model year F30 chassis vehicles. Designed to provide temporary extended mobility for a distance of 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss, the Potenza S001 RFT also delivers sports performance in dry and wet conditions. However, like all summer tires, they are not intended to be driven in near freezing temperatures, through snow or on ice.
Potenza S001 RFT tires feature an asymmetric design combining a large outboard shoulder, interlocking tread blocks and a central circumferential rib to enhance dry road steering response, high-speed stability and cornering precision. Notches in the shoulders expel water to the sides while high-angle lateral grooves in the intermediate ribs pump water into the wide circumferential grooves to help resist hydroplaning.
The tire’s internal structure features a lightweight belt package consisting of twin steel belts supported by a spirally wrapped aramid/nylon cord reinforcement that reduces rolling resistance, enhances ride quality and ensures high-speed durability. The internal structure of the Potenza S001 RFT also features Bridgestone Side Support Run-Flat technology reinforced sidewalls to temporarily support the vehicle after a puncture causes a loss of air pressure.
