PURPOSE: A device and a method for monitoring the condition of a tire are provided to transmit data at an optimal bit rate regardless of operation modes of a vehicle. CONSTITUTION: A device for monitoring the condition of a tire attached to a vehicle, comprises a tire condition sensor, a transmitting circuit(34), and a controller(31). The tire condition sensor measures a parameter indicating the condition of the tire. The transmitting circuit wirelessly transmits, at a variable bit rate, data representing the measured parameter. The controller controls the variable bit rate of the data transmitted by the transmitting circuit. The transmitter further comprises a vehicle speed sensor(33). The vehicle speed sensor detects a traveling speed of the vehicle, and the controller controls the variable bit rate depending on the detected traveling speed.
