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.
