Abstract: A run flat tire for use with a conventional wheel supporting an outer tire. First and second semi-circular shaped subassemblies inter-engage around an annular surface of the wheel, each of the subassemblies exhibiting an outer support ring adapted to engage a deflated inner surface of the outer tire in a run flat condition. The subassemblies exhibit stamped metal bodies and include stiffening beads for increased strength. Each of the subassemblies also includes a semi-circular shaped body cap exhibiting a flat band in end profile and which is secured to inner support locations associated with the spaced apart sides of the main body. Each of the subassemblies includes an innermost rim mounting ring secured to the wheel surface and exhibiting a cross sectional profile matching a selected wheel rim design.
