An improved wheel assembly for a track assembly of a crawler-type vehicle, and method of making the same, comprising a dual wheel set wherein each wheel of the set has a wheel disc with a central bolt circle portion, an intermediate generally conical portion extending outwardly from the central portion and an axially extending peripheral flange portion. A rim is mounted on said disc flange and preferably a rubber tire carried on the outer surface of the rim. The disc is a standard-type spun tapered truck wheel disc of current standard specification having an outwardly narrowing tapered cross-section. The rim comprises a cylindrical center section and a pair of inwardly extending, preferably slightly divergent peripheral edge flanges, and the rim is preferably secured to the disc peripheral flange by a circumferentially continuous weld at or near the axial center of the rim. The dual wheels of the set are mounted back-to-back relative to one another so as to be adapted to straddle a centrally located row of guide spikes of an associated track.
