This structure withstands the weight of the vehicle and its passengers for 50 miles up to 50 mph in case air pressure leaves the tire, due to a puncture or other damage. This ensures the tire's safer performance as it prevents the vehicle from being stranded on the side of the road. Instead, the tire can be driven on to reach a nearby garage where the damaged tire can be fixed or changed. These tires are not to be mounted on the same vehicle with regular tires.
