The SP Sport 600 is an Extreme Performance Summer tire developed for the 2008 Subaru Impreza WRX STI, the third generation of the rally-bred supercar powered by a 305-horsepower, 2.5-liter Subaru boxer engine. However, like all Extreme Performance Summer tires, these tires are not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
Dunlop’s warranty states: “Ultra high-performance summer tires are not recommended for winter use, and tread or shoulder cracking on those tires resulting from winter use will not be covered under our warranty.”
The SP Sport 600 features a high-grip, silica-reinforced tread compound molded into an asymmetric tread pattern featuring a rounded profile to combine ride comfort, handling and traction. Large outboard shoulder and continuous center ribs enhance initial responsiveness and cornering stability. Notched inboard intermediate and shoulder ribs are combined with three circumferential grooves to help resist hydroplaning. The tire’s internal structure includes twin steel belts reinforced by Dunlop’s JointLess Band (JLB) spirally wrapped nylon to blend high-speed durability with uniform ride quality.
