<p>A tire gauge includes: a bellows (1) telescopically mounted in an interior within a tire (7), a flexible indicator rod (2) protruding outwardly from and secured with a piston member (21) secured on a movable end portion of the bellows (1) slidably held in a guiding tube (30) either straightly or arcuately formed on an outer surface of the tire (7) or combinably secured with a filling valve (5) of the tire, so that the bellows (1) 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 (1) and the indicator rod (2) outwardly to a final balanced position for showing a true pressure data which is measured isothermally inside the tire. <IMAGE></p> |
