PROBLEM TO BE SOLVED: To provide a method of detecting abnormality of tire by which the abnormality occurring in a tire of a vehicle can be detected directly without receiving any influence from dirt etc., and the detected results can be informed to the driver of the vehicle. SOLUTION: Magnetic bodies 3 are arranged on the annular section 2 of the tire at prescribed intervals along the peripheral direction of the section 2 and, at the same time, a magnet 12 which forms an annular magnetic path across the annular section 2 is provided on the tire on the car body side. Then the electromotive force induced by a change in magnetic flux density in the annular magnetic path caused when the tire is rotated is measured, and the abnormality occurring in the annular section 2 of the type is detected from the measured waveform of the electromotive force.
