ABSTRACT:
This invention comprises an automatic, self-metering tire gauge having an air pressure gauge placed in the air flow path between a tire attachment piece and a filler needle valve. The gauge may remain attached to the tire at all times, including while air is being added to the tire. The gauge may be adjusted to indicate the pressure in the tire continuously whether or not the tire is being filled with air through the filler needle valve.
