A tire pressure monitoring apparatus includes a plurality of transceivers, a receiver and a warning device. Each transceiver is mounted on a respective wheel having a tire in a vehicle. The receiver is mounted on a body of the vehicle. The warning device receives a warning signal transmitted from the receiver. Each transceiver includes a sensing unit, a first control unit and a transmitting unit. The receiver includes a receiving unit and a second control unit. Each transceiver or the receiver includes a determination unit, which determines whether the tire pressure increases while the vehicle is parked. When the determination unit determines that the tire pressure is increased while the vehicle is parked, the second control unit calculates the selected threshold value, and stores the selected threshold value. |
