A pneumatic tire, after manufacture, is provided with a propellant material and a foam forming sealant material in its interior pressurizable space. The propellant and sealant are isolated from each other during normal running conditions of the tire and have no significant effect on the normal running characteristics of the tire. When a tire fails due to a puncture or the like, a loss of tire pressure and/or collapse of the tire structure and/or heat build up in the bead area due to friction permit the propellant and the foam forming materials to interreact. |
