ABSTRACT:
A method and apparatus for mounting and inflating an automobile tire on a rim assembly, the apparatus comprising a tire changing machine (11) having foot valve (32) and control means (12, 51) for limiting the air pressure developed within the tire during a step of sealing the annular beads of the tire to the flanges of the rim assembly. The control means delivers source air pressure, typically 120-200 PSI at most shops, to the fill line (34) of the tire changing machine during sealing and inflating without substantially diminishing the source air pressure delivered thereto. The control means rapidly and frequently compares the pressure attained within the tire with a selected pressure, and once the selected pressure has been attained, the control means cuts off further delivery of source air pressure. An audible alarm (72) is provided to indicate that pressurized air is flowing and to indicate that the desired pressure level has been achieved within the tire.
