A tire pressure indicator carried on a tire being monitored for inflation pressure. The indicator includes a housing enclosing an indicating member bearing color coding corresponding to proper inflation. Preferably, additional color coding is provided corresponding to excessive tire pressure and to low or inadequate tire pressure. The indicating member occupies a chamber and air pressure from the tire acting on the indicating member, and is moved in response to tire pressure such that the appropriate color coding is revealed through a window formed in the housing.
