Tire valve assembly

A tubeless tire valve assembly for mounting within an aperture in a tire rim for a tubeless tire, said valve assembly comprising an elongated generally cylindrical valve stem of rigid material having a first substantially radial annular flange portion proximate one end defined by a pair of annular surfaces lying in substantially parallel spaced planes disposed substantially perpendicular to the longitudinal axies of said valve stem, said valve stem having a reduced diameter outer surface portion said first flange portion, said valve stem further defining an internal thread proximate the end thereof opposite said one end for threadingly receiving a valve core having a mating external thread, and a generally tubular rubber body molded about said valve stem and said first flange portion so as to be adhered to said pair of said annular flange surfaces and at least a portion of the length of said valve stem extending from said flange portion toward said opposite end and including said reduced diameter outer surface portion, said rubber body being operative to trap said valve stem within said rubber body and having at least one exterior annular recess formed therein intermediate said first annular flange portion of said valve stem and said opposite end thereof, said annular recess being adapted for sealing contact with the surface of a tire rim with said first annular flange disposed on the internal side of the tire rim, said first annular flange having a diameter approximately equal to the diameter of the portion of said rubber body received through the tire rim aperture so as to substantially prevent the tubeless tire valve from being blown out of the rim aperture.
