ABSTRACT:
An apparatus for maintaining a spare tire in the trunk of a vehicle fully inflated. A conventional spare tire has a metal wheel with a rubber inflatable tire attached thereto and a valve stem extending out of the bottom on one side thereof. An extension tube sealingly attached at one end thereof to one end of the valve stem on one side of the wheel extends to the other side of the wheel through a rubber washer disposed in one of the lug holes. A one-way valve stem is disposed in the other end of the extension tube for permitting inflation of the tire through the extension tube. A pressure gauge is connected to the extension tube adjacent to the one-way valve for constantly showing the air pressure inside of the tire.
