This tire features a reinforced internal structure that provides a limited temporary performance in case of air pressure loss. Once air pressure leaves the tire, it can be driven on for 50 miles up to the speed of 50 mph, as the construction withstands the weight of the vehicle and its passengers. This enables the tire's safer performing ability throughout its performance. Run flat tires are manufactured for vehicles without space for a spare tire, and their heavier construction prevents them from being mixed with regular tires on the same vehicle.
