Bridgestone Potenza S001245/40ZR20
The Potenza S001 is Bridgestone’s Max Performance Summer tire developed as Original Equipment for premium high-performance sports cars, coupes and sedans. The Potenza S001 is designed to combine low rolling resistance efficiency with maximum sports performance in dry and wet conditions. However, like all summer tires, they are not intended to be driven in near freezing temperatures, through snow or on ice.
The Potenza S001 features an asymmetric design combining a large outboard shoulder, interlocking tread blocks and a central circumferential rib to enhance dry road steering response, high-speed stability and cornering precision. Notches in the shoulders expel water to the sides while high-angle lateral grooves in the intermediate ribs pump water into the wide circumferential grooves to help resist hydroplaning.
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 reduces rolling resistance, enhances ride quality and ensures high-speed durability. Active rubber inserts in the sidewalls near the bead areas tune vertical sidewall stiffness to blend cornering grip with ride comfort, as well as increase longitudinal stiffness to generate straight-line braking forces.
