The Dunlop SP Sport 600 is a top performance summer tire designed and developed for the third generation rally-bred supercar 2008 Subaru Impreza WRX STI. This tire is a combination of ride comfort, handling and traction due to its rounded profile feature and high-grip, silica-reinforced tread compound shaped into an asymmetric tread pattern. It also has twin steel belts, reinforced with Dunlop's JointLess Band (JLB) spiral wrapped nylon, large outboard shoulder blocks and continuous center ribs to provide improved steering response as well as cornering stability, ride quality and durability even at high speed. With the combination of three circumferential grooves, shoulder ribs and notched inboard intermediate aids to weather hydroplaning. As with all summer tires, it is not designed to be driven in snow, ice or near freezing temperatures.
