Abstract: The combination tire valve and pressure gauge of the present invention is formed to be substantially the same size as current tire valve stems, such that it may be used as a replacement part therefore. The device includes a pressure sensitive bellows disposed within the stem, the movement of which is counteracted by a calibrated spring. Movements of the bellows, caused by changes in the tire pressure, are mechanically translated to a rotary motion of a pressure indicator. A window is formed in the tire stem to permit viewing of the pressure indicator, whereby different numerals corresponding to different tire pressures become visible in the window upon rotation of the indicator which is caused by movement of the bellows. An air channel is formed through the device to permit air to be pumped into the tire. A rotary indicator having an internal spiral groove rotates upon a driving rod formed with projecting driving pin members that project into the spiral groove to cause the rotation of the indicator.
