Title: Expandable tire rim arrangement and method of installation

Abstract: An expandable tire rim arrangement is disclosed including a transversely split tire supporting rim having an outer peripheral tire engaging surface, an inner peripheral surface, and relatively circumferentially movable ends disposable between a rim diameter reducing position for ease of insertion of the supporting rim axially into a tire and a rim diameter increasing position, and a rim expanding and wheel mounting assembly having diametric dimensions somewhat larger than the diameter of the inner peripheral surface of the supporting rim when in its diameter reducing position and being axially slidably insertable into the supporting rim for tightly expanding it against the tire.
