    • There is provided a wheel diameter variation-detecting device which is capable of properly detecting relative variation in diameter between a plurality of wheels of a vehicle. The wheel diameter variation-detecting device 1 for detecting variation in diameter between a plurality of wheels WFL, WFR, WRL, WRR of a vehicle V which rotate independently of each other detects rotational speeds NFL, NFR, NRL, NRR of the respective wheels WFL, WFR, WRL, WRR, and calculates a variation parameter RDR indicative of variation in diameter between the wheels WFL, WFR, WRL, WRR, using one of the wheels WFL, WFR, WRL, WRR as a reference wheel WRL, based on a result of comparison between the rotational speed NRL, NRR of the reference wheel and that of one of the wheels other than the reference wheel (step 3). Further, the wheel diameter variation-detecting device learns the variation parameter based on a value obtained by averaging a plurality of values of the variation parameter RDR obtained before the detected travelled distance DISSUM reaches a predetermined distance DIS2 (steps 4, 31 to 33, 36, 44).
