ABSTRACT:
A safety support for mounting on a split rim inside a tire chamber to resiliently support the tread portion of the tire in the deflated condition and maintain the bead portions of the tire in separated positions. The support is in the form of an annular ring of resilient material having a base with a relatively wide radially inner surface for seating on the rim and separating the bead portions. A flange extends radially inward from the radially inner surface of the base for gripping by the rim sections to seal the space within the tire and retain the ring on the rim. The radially outer portion of the support has a diameter less than the diameter of the tread portion of the tire in the deflated condition and greater than the diameter of the base portion. The base portion may be of greater width than the radially outer portion and be connected to the outer portion by an intermediate supporting portion of circumferentially spaced-apart radially extending ribs for cushioning the vehicle on which the tire, safety support and rim assembly are mounted.
