<p>A road wheel for a track-laying vehicle which comprises a metal disc wheel including a wheel mounting disc, a rim extending axially from the periphery of the disc and a strengthening flange projecting radially inwardly from the disc-remote edge of the rim. An overlay body of foamed elastomeric material is molded onto the disc wheel to fill the area between the disc, rim and flange, and thereby prevent accumulation of mud in this area. The outboard surface of the overlay body is pitched axially from the disc to the rim to self-clean as the wheel is rotating. A solid rubber tire is carried externally of the rim.</p> |
