Abstract: A method and system to monitor tire conditions in a vehicle when the vehicle is traveling in and out of RF coverage zones provided by one or more remote monitoring stations uses one or more sensor assemblies on the vehicle to sense conditions such as pressure or temperature. When the vehicle is not within the RF coverage zone of a remote monitoring station, sensor data generated at the sensor assemblies is stored on a communication module mounted on the vehicle. The sensed data is sent to the remote monitoring station once the vehicle enters the RF coverage zone. Regardless of whether the vehicle is in an RF coverage zone, the driver of the vehicle can still monitor tire conditions via a display in the vehicle that shows tire conditions. Two-way communication between the remote monitoring station and the sensor assemblies allows remote adjustment of operation of the sensor assemblies.
