The Potenza RE050A Pole Position RFT (Run Flat Tire) is Bridgestone's Max Performance Summer run-flat tire developed exclusively for the Chevrolet Corvette C6 ZO6. The Potenza RE050A Pole Position RFT is designed to combine athletic capabilities on the street along with temporary extended mobility for a distance of 50 miles at up to 50 mph even in the event a puncture allows complete air pressure loss. Like all summer tires, the Potenza RE050A Pole Position RFT is not intended to be driven in near-freezing temperatures, through snow or on ice.The Potenza RE050A Pole Position RFT features a high-silica content tread compound molded into an asymmetric tread design with stable shoulder elements, large tread blocks and a continuous center rib on the outboard side to provide responsive handling and traction on dry roads, while wide circumferential and lateral tread grooves pump water out from under the tire's footprint to enhance hydroplaning resistance and aid wet traction. Another continuous circumferential rib adjacent to the inboard shoulder blocks enhances wear quality to help reduce noise throughout the life of the tire, especially on cars with alignment settings that specify negative camber. The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon to stabilize the tread area and enhance high-speed capability, as well as Bridgestone self-supporting run-flat technology specifically tuned to support the Chevrolet Corvette C6 ZO6 even after a puncture causes a complete loss of air pressure.
