  "textContent": "A tire monitoring apparatus (1) includes transponders (30) and a transmitter-receiver (40). Each transponder is provided in one of the tires (20) of a vehicle, and the transmitter-receiver is mounted on the body frame of the vehicle. In response to a predetermined interrogating radio wave, each transponder (30) detects a condition of the corresponding tire and wirelessly transmits data representing the detected condition of the tire. The transmitter-receiver (40) transmits the interrogating radio wave and receives data wirelessly transmitted by each transponder (30). In a part of a period during which the corresponding tire rotates through one revolution, each transponder passes through a communication range. The transmitter-receiver changes the time interval at which the interrogating radio wave is transmitted such that the interrogating radio wave is transmitted while the transponder (30) is in the communication zone. As a result, the conditions of the tires are always monitored in a reliable manner.",
