ABSTRACT:
A vehicle wheel rim device of a type in which a first wheel rim carries a first tire casing, and having a second tire casing inwardly of the first tire casing, characterized by the provision of a second rim inwardly of the first rim, the generally circular edge-portions of the second rim being supported by the generally cylindrical body portion of the first rim, and are spaced from the adjacent circular edge-portion of the first rim, and providing that the circular edge-portions of the second rim provide support for the bead-portions of the second tire casing in a manner in which the second tire casing bead portions are substantially spaced, respectively from the beam portions of the first tire casing, thus protecting the inward tire casing from the erratic flopping of the outer tire if it becomes disabled.
