The ContiSportContact 3 SSR (Self Supporting Runflat) is Continental Tire's Max Performance Summer run-flat tire designed to provide temporary extended mobility in case of complete air loss due to a puncture. The ContiSportContact 3 SSR is designed to combine outstanding braking capability and agile steering precision. Like all summer tires, the Continental ContiSportContact 3 SSR is not intended to be driven in near-freezing temperatures, through snow or on ice.ContiSportContact 3 SSR tires permit drivers to remain mobile in the event of a flat tire by allowing them to reach their destination or tire service facility without having to replace a flat tire with the spare tire. The ContiSportContact 3 SSR's reinforced sidewall enables the car to continue on its way at a maximum speed of 50 mph (80 km/h) for up to 50 miles (80 km), depending on road conditions and vehicle weight.ContiSportContact 3 SSR tires feature an asymmetric design with solid tread blocks and a continuous rib on the outboard shoulder to improve responsiveness and cornering stability, while continuous intermediate ribs provide constant rubber-to-road contact to reduce noise and control the longitudinal forces experienced when braking. The continuous circumferential tread grooves help disperse water to resist hydroplaning and their asymmetrically angled walls further stabilize the tread ribs, increasing steering precision and reducing deformation while cornering. The notched shoulder blocks on the inboard portion enhance wet weather traction.The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon to stabilize the tread area promoting uniformity and high-speed durability along with reinforced self-supporting sidewalls that prevent the inside of the tire from getting pinched between the road and the rim in the event of a loss of inflation.
