An apparatus for inflating a tire including a base and a tire inflation line coupled with a pressure sensor. An air blast assembly includes a blast line fluidly coupled to a blast nozzle located on the base and configured to receive and direct pressurized gas from the blast line when the blast nozzle is in an air blast position relative to a tire and wheel assembly supported on the base. A device controller can monitor the pressure of a tire and wheel assembly and sense whether an effective tire bead seal has been formed. The device controller can generate a blast signal when no seal has been formed. A gas flow controller coupled to the air blast assembly and the device controller can be responsive to the blast signal to cause a blast of pressurized gas to be released from the blast nozzle to create an effective tire bead seal.
