The Potenza RE-71R is an Extreme Performance Summer tire developed for serious sports car, sports coupe and performance sedan driving enthusiasts looking for Bridgestone's fastest DOT-legal street radial. Starting with a clean-sheet approach and a virtual slick tread, all of the design features were fine-tuned to maximize performance, traction, handling and control. Performance-tuned for dry and damp conditions, the Potenza RE-71R, like all Extreme Performance Summer tires, are not intended to be serviced, stored or driven in near- and below-freezing temperatures, through snow or on ice.
