An endless track unit for a tracked vehicle has guide wheel assemblies which support the track. A guide wheel assembly includes a hub adapted to be rotatably mounted on an axle, the hub having axially-spaced outer flanges of an outer diameter no greater than a first diameter. A central flange on the hub extends radially outwardly beyond the first diameter. A pair of outer axially-spaced wheels are mounted on the outer flanges and a central ring-like wheel having an inner diameter greater than the first diameter is secured to the central flange. The hub is generally an integral, or unitary, element adapted to be mounted on an axle and supports all three wheels. The wheels are substantially rigid rings, and each has an elastomeric covering formed about its periphery for cushioned engagement with the track.
