The Potenza S-04 Pole Position is Bridgestone's Max Performance Summer tire developed for the drivers of ultra high performance sports cars, coupes and sedans who want to feel the rush of driving their vehicle. Potenza S-04 Pole Position tires are designed to perform in warm, wet and dry conditions. However like all summer tires, they are not intended to be driven in near freezing temperatures, through snow or on ice.The Potenza S-04 Pole Position features an asymmetric tread design with a large outboard shoulder, interlocking tread blocks and a central circumferential rib to enhance dry road steering response, high speed stability and cornering precision. High angle tread blocks in the intermediate ribs promote longitudinal stiffness to enhance straight-line braking forces while slanted lateral grooves pump water into wide circumferential grooves to help resist hydroplaning. Another continuous circumferential rib adjacent to the inside 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 features a lightweight belt package consisting of twin steel belts supported by a spirally wrapped aramid/nylon cord reinforcement that enhances ride quality and high speed durability. Active rubber inserts in the sidewalls near the bead areas tune vertical sidewall stiffness to blend cornering grip with ride comfort.
