A tire air pressure monitoring system includes: a sensor unit mounted to a tire and including: an air pressure sensor for outputting a tire air pressure, and a transmitter, a receiver for receiving a radio wave from the sensor unit; a tire air pressure monitoring controller for warning a vehicular occupant of a tire air pressure decrease when the tire air pressure is less than or equal to a warning threshold. A puncture sensor for sensing a puncture of the tire, and a puncture repairing agent use sensor for sensing whether or not the puncture is repaired by using a puncture repairing agent after the puncture is sensed. When the puncture repairing agent use sensor senses that the punctured tire is repaired using the puncture repairing agent, the tire air pressure monitoring controller continues the warning even though the tire air pressure from the air pressure sensor is normal.
