The wheel adapter includes an adapter plate having a plurality of holes therethrough in a bolt circle. The holes are adapted to respectively receive the wheel mounting studs. The wheel adapter further includes a plurality of studs protruding from the adapter plate and arranged so as to extend through at least some of the holes in the wheel.
