Some tires have the ability to maintain mobility when punctured. Three technologically advanced tires are self-sealing, self-supporting, and tire / wheel combination systems.
Self-Sealing. Self-sealing tires have a special lining inside that will permanently seal most small nail or screw punctures.
Self-Supporting Tires. Self-supporting tires are designed with a stiff internal construction, generally carrying the weight of the vehicle for about 50 miles (80 km) even if the tire loses all air pressure.
Tire/Wheel Combination Systems. Tire/wheel combination systems use a special tire and wheel assembly that has a support ring to carry the weight of the vehicle if the tire loses air pressure. These assemblies allow the vehicle to be driven about 125 miles (201 km) with no air pressure.
