The SP Sport 7010 A/S DSST is an Ultra High Performance All-Season run-flat tire featuring Dunlop Self-Supporting Technology (DSST) developed as Original Equipment (O.E.) for the all-wheel drive Nissan GT-R super sports car as part of its Cold Weather Package. The SP Sport 7010 A/S DSST was designed to provide temporary extended mobility for a distance of 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss, as well as year-round traction, even in occasional light snow.
The SP Sport 7010 A/S DSST features an all-season, silica-reinforced tread compound molded into an asymmetric tread pattern to combine handling and traction. Large outboard shoulder blocks and continuous center ribs enhance initial responsiveness and cornering stability. Independent 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. SP Sport 7010 A/S DSST tires feature reinforced sidewalls that are designed to temporarily support the weight of the car even after a loss of air pressure.
