A tire pressure monitoring system comprises: a first abnormality determination means (S2) for determining a state to be normal in which the front wheel air pressure is higher than a front wheel warning threshold 400 [kPa] and the rear wheel tire pressure is higher than a rear wheel warning threshold 240 [kPa], and for turning on a warning light (6) in the state; and a second abnormality determination means (S3, S4) for continuing the warning light (6) to an off state regardless of the determination result of the first abnormality determination means when the warning light (6) is turned off while the vehicle is stopped, the tire pressures of two wheels have been determined to be higher than the front wheel warning threshold 400 [kPa], and the tire pressures of the remaining two wheels have been determined to be higher than the rear wheel warning threshold 240 [kPa]. |
