Bridgestone Potenza RE050A I RFT


The Potenza RE050A I RFT (Run-Flat Tire) is Bridgestone's Max Performance Summer run-flat tire developed exclusively for selected BMW Z4 vehicles, as well as 3 Series cabriolets, coupes and sedans equipped with BMW's sport package. The Potenza RE050A I RFT is 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 RE050A I RFT is also designed to combine responsive and predictable handling with good traction on dry and wet roads. It is not intended to be driven in near-freezing temperatures, through snow or on ice.

The Potenza RE050A I RFT features a high-grip tread compound molded into an asymmetric tread design. Stable outboard shoulder elements, intermediate tread blocks and a continuous center rib provide responsive handling, high-speed stability and traction on dry roads, while circumferential and lateral tread grooves pump water out from under the tire's footprint to minimize hydroplaning and aid wet traction. A continuous rib adjacent to the inboard shoulder promotes even wear and resists inside wear generated by suspensions that specify negative camber alignment settings.
