Bridgestone Dueler H/P Sport Run Flat is a high-performance summer tire for light and medium trucks. It is made with a special low resistance sidewall compound that provides comfortable and quiet performance with extra safety. Its tread design features large shoulder and intermediate blocks with two continuous center ribs to provide responsive handling and stability on dry roads. The wide circumferential grooves help water flow through the tire's track to reduce hydroplaning and increase wet traction. Dueler H/P Sport’s twin steel belts spirally-wrapped by nylon with hard sidewall filler between polyester cord piles help resist bends at high speeds while cornering.
