Abstract: Pneumatic rubber tire with a puncture sealing feature comprised of an enveloped open network structure containing a sealant composition on the inner portion of the tire.

Abstract: A safety support system in which an annular safety support of resilient material having an outer diameter less than the inner diameter of the tire is positioned around a rim and within the tire. The resilient material of the safety support is under pressure and reinforcing cords are wrapped around the annular safety support to control expansion and maintain the safety support in position between the bead portions in the deflated condition of the tire. The resilient material may be of foam having closed cells containing gas under pressure or it may be a generally solid material which is compressed upon installation or formed under pressure in the tire. The safety support may also have safety support flanges at the edges for positioning between folded portions of the tire sidewalls during operation of the tire in the deflated condition.

Abstract: A safety support system for a tubeless tire and rim assembly which is adaptable for field mounting of the tire on the rim. The tire cavity within the tire contains a safety support body made up of an outer ring member and an inner ring member. The outer ring member is of resilient foam material providing cushioning and support of the tire. The inner ring member is of a substantially incompressible material which is flowable for injection into the tire cavity of the outer ring member and maintain the bead portions of the tire on said bead seats of said rim during operation.

Abstract: A safety support system in which an annular safety support of resilient foam material having an outer diameter less than the inner diameter of the tire is positioned around a rim and within the tire. The foam material has closed cells containing gas under pressure for supporting the tire in the deflated condition and expanding in an axial direction to press the bead portions against the bead seats of the rim. The safety support has beads and a fabric reinforced construction at a radially outer wall for controlling expansion beyond the radially outer diameter. A second reinforcing fabric ply may be provided at the radially inner wall for controlling expansion and facilitating field mounting of the safety support.

Abstract: A self-sealing pneumatic tire which comprises a tire casing having an integral, thin gauge, resilient closed cell structure disposed in its inward portion. Such a tire structure has particular utility for sealing against puncturing objects.

Abstract: A tire/wheel assembly comprised of (A) a pneumatic tire axially mounted on a centered, wheeled rim, said assembly having attached therein a receptacle containing a coolant composition comprised of water and a low molecular weight polyethylene glycol, and (B) means for releasing said coolant composition onto the inner surface of said pneumatic tire. The invention has a particular purpose of inhibiting or retarding a rapid rate and temperature build-up caused by pneumatic tire being at least partially inflated primarily due to a reduction in its inflation pressure.
