A tire-side apparatus includes: a first storage unit storing an identifier for identifying the tire-side apparatus. A signal reception strength measurement unit measures signal reception strengths of measurement signals. A specification unit specifies the number of received measurement signals. A second storage unit stores the number of the received measurement signals transmitted sequentially from a vehicle body-side apparatus to tire-side apparatuses corresponding to a plurality of tires, and a signal reception order in which the measurement signal with the highest signal reception strength among the received measurement signals was received. The tire-side apparatus transmits a response signal including an identifier and information indicating the reception order and number of measurement signals stored in the second storage unit, and the vehicle body-side apparatus determines a correspondence based on comparison of the information indicating the number of measurement signals and signal reception order transmitted from the multiple tire-side apparatuses.
