The ContiSportContact 5 SSR SUV is Continental's Street/Sport Truck Summer run-flat tire designed to provide temporary extended mobility in case of complete air loss due to a puncture. Initially developed to match the sporty driving characteristics of BMW crossover vehicles, ContiSportContact 5 SSR SUV tires are designed to offer short braking distances and good cornering traction in moderate to warm ambient temperatures. However, like all summer tires, it is not intended to be driven in near freezing temperatures, through snow or on ice.ContiSportContact 5 SSR SUV 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 5 SSR SUV'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 ContiSportContact 5 SSR SUV uses Continental's Black Chilli compound molded into an asymmetric tread design that features a macro-block outboard shoulder that adapts to the road surface to improve road grip and cornering stability. Four circumferential grooves channel water to resist hydroplaning and enhance wet traction. A continuous center rib and notched intermediate ribs promote steering response and straight-line tracking.Continental's Black Chilli compound's short-chain polymers react to braking forces by building heat to shorten braking distance on wet and dry roads, while the compound's long-chain polymers release the absorbed energy more efficiently at constant speeds to reduce rolling resistance. Thus, the tire stops faster and remains cooler for longer life and reduced fuel consumption. The tire's internal structure features twin steel belts reinforced with spirally wrapped polyamide (a mixture of heat-resistant synthetic aramid fiber and nylon threads) that enhance the ride quality while tuning the contact area's vertical flexibility and lateral rigidity. Reinforced self-supporting sidewalls 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.
