Abstract
A method and system for managing tire pressure in a vehicle are disclosed. The system is a tire pressure monitoring system associated with the tire pressure sensors. The method includes the general steps of informing the operator that air pressure in a tire is below a desired level, causing the sensor to undertake a rapid sampling of pressure of the tire during an interim state while the vehicle is being driven, advising the operator to manually add pressure to the tire in discrete increments of, for example, between 5 and 10 seconds, causing the sensor to undertake a rapid sampling of tire pressure while air is being manually added to the tire, and causing the sensor to transmit tire air pressure data until the operator stops adding air. The method may also include the step of providing the operator with feedback when a predetermined tire air pressure is reached.
