A wheel to provide an adjustable track for a vehicle comprises a wheel disc and a rim interconnected by a plurality of circumferentially spaced connections. The connections each comprise a channel member spaced about the rim and receiving a connecting block attached to the periphery of the disc. The channel members are orientated to be parallel to the rotational axis so that forces transmitted from the disc to the rim do not induce forces along the rotational axis. Releasable stops are provided to allow the blocks to be displaced along the channel members and vary the track of the vehicle.
