ABSTRACT:
A tire gauge includes: a bellows telescopically mounted in an interior within a tire, a flexible indicator rod protruding outwardly from and secured with a piston member secured on a movable end portion of the bellows slidably held in a guiding tube either straightly or arcuately formed on an outer surface of the tire or combinably secured with a filling valve of the tire, so that the bellows will be subjected to a pressure inside a tire at a real temperature in the tire interior and the tire pressure will urge the bellows and the indicator rod outwardly to a final balanced position for showing a true pressure data which is measured isothermally inside the tire.
