A wheel-state obtaining apparatus including wheel-side devices each operable to transmit wheel-side information in response to an abrupt change of a tire air pressure of a corresponding one of wheels, when the tire air pressures of the wheels are abruptly changed in a predetermined order by an operator of the apparatus, and a body-side device operable to receive the wheel-side information from the wheel-side devices in the same order, and obtain wheel-position information indicative of a position of each wheel, on the basis of the predetermined order and a state of reception of the wheel-side information, so that the wheel positions and the wheel-side devices can be automatically correlated with each other, with high accuracy and reliability, by simply changing the tire air pressures of the wheels in the predetermined order. |
