The Potenza RE970AS Pole Position is Bridgestone's flagship Ultra High Performance All-Season tire developed for drivers looking to combine high speed capability with all-season traction for sophisticated sports cars, sporty coupes and high performance sedans. The Potenza RE970AS Pole Position is designed to provide predictable handling, traction and control on dry and wet roads, as well as in occasional light snow.The Potenza RE970AS Pole Position molds a new all-season rubber compound into a directional tread design that combines responsiveness on dry roads with traction in wet and wintry driving conditions. Notched shoulders, stable tread blocks and a continuous center rib increase tread stiffness to deliver responsive steering, predictable handling and at-the-limit braking on dry roads. A series of circumferential and lateral grooves help pump water and slush through the tire's footprint to enhance hydroplaning resistance, wet road and light snow traction.The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon, along with a casing reinforced by a hard sidewall filler between polyester cord plies to help resist distortion at high speeds and while cornering.
