Methods of monitoring tire pressure and responding to a tire pressure error. A tire pressure monitoring apparatus provides signals to a vehicle control representing pressures in respective ones of the tires. The vehicle control first detects a tire pressure error in one of the tires, and then presents to a user a first signal representing the tire pressure error in the one of the tires. Then, a user input representing a prospective tire filling activity is detected. Thereafter, a second signal is presented to the user in response to a pressure in the one of the tires being substantially equal to a desired tire pressure.
