Abstract: This invention is an automatic shut-off valve and gauge for tires during inflation. Configured as a double stem valve joined either on the outside or inside the rim of the tire. One stem serves as an air valve for inflating tires with a metal or plastic line attached to it extending into the second stem, which is a valve that regulates the air pressure in the tire. Air supplied during inflation of the tire causes a linkage to move and open a vent to the atmosphere which was otherwise closed. A spring loaded valve is designed to open when the air pressure in the tire exceeds the correct operating pressure and to allow excess air to escape to the atmosphere. A retracting and extending indicia is provided on the top of a spring loaded valve to indicate when the tire is properly inflated to a preset pressure.
