The track assembly comprises a plurality of wheels which comprises a drive wheel and a plurality of roller wheels, as well as an elastomeric endless track disposed around the plurality of wheels for engaging the ground. A roller wheel may comprise a wheel body and a covering on the wheel body. The covering may comprise a lateral portion dimensioned to contact a drive/guide lug of the track. The roller wheels and the track may implement a self-alignment system of the track assembly. The track assembly may comprise a cooling system for transferring heat away from a roller wheel. The track assembly may comprise a lateral motion mechanism allowing a roller wheel to move widthwise in response to a side load.
