  • Method and apparatus for replacing a tire valve stem without having to raise the vehicle, remove the wheel, or tire from the wheel
    Patent number: 9272588
    Abstract: A method for replacing a leaking valve stem includes the steps of cutting a part of the valve stem external to a hollow interior of a tire at the external surface of a wheel/rim so that a base of the valve stem falls into the hollow interior of the tire and so that a wheel aperture is exposed. A replacement valve stem has a radially expandable base, a main body of frusto-conical shape, and an annular step is formed where the base meets the main body. Wrench-engageable flats are formed in a narrow end of the main body and an internally threaded boss is secured to the wrench-engageable flats. The radially expandable base is inserted into the wheel aperture and the annular step abuts an exterior surface of the wheel/rim. The expandable base is then expanded until the wheel/rim is tightly sandwiched between the expanded base and the annular step.
