A system and method for remote monitoring of tire pressure provide an indication of optimal tire pressure when a tire inflation valve is actuated. A tire monitor mounted a tire includes sensors for sensing tire pressure and temperature, and a transmitter for transmitting wireless tire information signals having tire pressure and tire temperature data. A controller mounted on board the vehicle determines an optimal pressure for the tire based on the temperature data and vehicle load information. The controller generates a control signal for use in providing an audible and/or visual indication during tire pressure adjustment when the sensed tire pressure represented by the tire pressure data is substantially equal to the determined optimal tire pressure.
