A tire pressure gauge has a tube member with first and second open ends, in which a diaphragm member is provided crosswise and suspended by a spring to sense the pressure of a tire. An indicator rod is movably provided lengthwise to be actuated by the diaphragm to extend outwardly through the second open end for visible indication. A writing and a time-indicating devices are incorporated with the gauge to act multi-functions of the gauge.
