Abstract
A system for monitoring tire pressure of a vehicle or fleet of vehicles includes a check point through which the vehicles pass. A first interrogation component is positioned proximal the check point and tire pressure monitoring devices associated with the tires of the vehicle are in communication with the first interrogation component. An identification tag associated with the vehicle stores data unique to the particular vehicle and is also in communication with the first interrogation component. Likewise, a data collection device communicates with the interrogation component as well. Finally, an alarm communicates with the interrogation component to alert an operator when the tire pressure falls outside a predetermined range.
