A wheel for a track assembly of a tracked vehicle, such as, for example, an all-terrain vehicle (ATV), a snowmobile, a construction vehicle or an agricultural vehicle. The wheel in use is one of a plurality of wheels of the track assembly. The track assembly comprises an endless track disposed around the plurality of wheels, comprising an inner side for facing the plurality of wheels and a ground-engaging outer side for engaging the ground. The wheel comprises a wheel body comprising a hub portion, a rim portion, and a radially-extending portion between the hub portion and the rim portion. The wheel also comprises a covering on the body. The covering in use contacts the endless track's inner side. A material of the covering is different from a material of the wheel body. The wheel body and the covering may be mechanically interlocked. The covering may comprise a peripheral portion covering at least part of a peripheral side of the wheel body and a lateral portion covering at least part of a lateral side of the wheel body.
