ABSTRACT:
An apparatus for filling and removing liquid ballast from a tire comprises a fluid circuit including a pressurized air tank and a liquid storage tank each operatively connected to an adapter releasably attached to the rim of a tire in lieu of its conventional valve stem. During removal of the liquid ballast, pressurized air is communicated through the adapter to pressurize a closed chamber of the tire to pump the liquid ballast to the storage tank. Upon refilling of the tire, pressurized air is communicated to the storage tank to pump liquid back into the tire.
