The strengthened internal structure allows the tire to withstand the weight of the vehicle and its passengers, in case of air pressure loss. This enables the tire to securely perform for 50 miles up to 50 mph, once air pressure leaves the tire. In other words, the tire can still be driven on for limited temporary performance. The tire prevents the vehicle from being stand on the side of the road, allowing the tire to improve driving safety levels. At the same time, run flat tires should not be mounted on the same vehicle as regular ones.
