The tire's reinforced internal structure strengthens the tire to be able to withstand the vehicle's weight in case of air pressure loss. In this manner, the tire can be used for 50 miles up to the speed of 50 mph after the air pressure leaves the tire, preventing the driver from being stranded on the side of the road. These tires have a heavier construction and as a result, they cannot be mixed with regular tires on the same vehicles.
