Abstract
A method for removing a dual wheel from a primary wheel of a dual wheel assembly. The dual wheel is secured to the primary wheel while forming a gap between a periphery of the dual wheel and a periphery of the primary wheel. The dual wheel and the primary wheel each may have a tire mounted thereon, with the dual wheel assembly being carried on an axle. The method comprising inserting an uninflated, high pressure airbag at least partially into the gap between the dual wheel and said primary wheel; inflating the high pressure airbag to expand the gap between the dual wheel and the primary wheel so as to separate the dual wheel and the primary wheel; and finally, removing the dual wheel from the primary wheel. Likewise, a similar method can be used to remove a wheel from an axel, the wheel being carried on and secured to the axel while forming a gap between a periphery of the wheel and a periphery of the axel.
