1. A tire purge/fill apparatus for both purging air from a tire to be filled and for filling a tire with a gas to a pre-determined pressure, the apparatus comprising: a supply of gas for filling a tire to be filled; a filter member coupled in fluid communication with said supply of gas for filtering the gas before entry into the tire to be filled; a valve mechanism for controlling the purging and filling operations; a vacuum pump coupled in fluid communication with said valve mechanism; and a supply hose coupled to said valve mechanism for attachment to the tire to be purged and/or filled; said valve mechanism including at least one user selectable member positionable so as to effect either a filling operation or a purging operation, said valve mechanism providing filtered gas to said supply hose for filling a tire with gas when said at least one user selectable member is positioned so as to effect a filling operation, and said valve mechanism activating said vacuum pump and drawing a vacuum through said supply hose for purging a tire of air when said at least one user selectable member is positioned so as to effect a purging operation.
