(GI. ?ll-63) The invention relates to a wheel body and rim organization and more particularly to such an organization adapted for the mounting of heavy duty pneumatic tires. It is among the objects of the invention to pro vide a device of this class which facilitates the inclined portion of the disc wheel Mdy adjacent its merger withthe generally axially extending peripheral ?ange and the flange itself, with the outboard margin or said ?xed rim section and the securement of the nested overlapping por tions of the wheel body and by two axially spaced annular lines of securement.
