A tire state judging device includes wheel speed sensors configured to detect rotational speeds of tires, and a control unit configured to perform frequency-analysis of detection results of the wheel speed sensors to detect a frequency of a valley part of an output, and calculate an air pressure of the tire from the detected frequency of the valley part. According to this, the tire state judging device has an effect that this can detect a state of the tire irrespective of a state of a road surface.
