The ContiProContact SSR (Self Supporting Runflat) is Continental's Grand Touring All-Season run-flat tire designed to provide temporary extended mobility in case of complete air loss due to a puncture. The ContiProContact SSR is designed to blend good looks, low noise and the assurance of extended mobility along with the versatility of all-season traction, even in light snow.ContiProContact 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 ContiProContact 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.The ContiProContact SSR features an all-season tread compound molded into a symmetric, notched-rib tread design that provides continuous tread contact with the road to enhance steering response and handling while its wide circumferential grooves promote hydroplaning resistance and wet traction. Continental's PROactive Edge Technology places at least 800 arched edges in each ContiProContact SSR tire's tread design to bring more active edges into the contact patch to promote stormy-weather traction while allowing the pattern elements to transfer smoothly from edge to edge to minimize on-road noise.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.Though they cannot be labeled as run-flat tires, tires branded with MOExtended or MOE on their sidewalls offer run-flat-like characteristics by delivering limited temporary extended mobility after a puncture results in complete loss of air pressure. Because MOExtended or MOE tires do not have the same speed and distance endurance of conventional run-flat tires, they should not be substituted in any situation where a conventional run-flat tire is required.
