Abstract:
1. A tire distortion detecting method for detecting a distortion of a rotating tire by using a tire, in which a plurality of conductor pieces embedded in lines at predetermined intervals in a circumferential direction of the tire are embedded in two or more different layers, and a monitoring device which has a scanner unit provided in a tire house of a vehicle, characterized in that the monitoring device radiates a pulsed electromagnetic wave from the scanner unit to a surface of the conductor piece along the line of the conductor pieces in each of the layers, causes the scanner unit to receive the pulsed electromagnetic wave reflected from the conductor piece in each of the layers and a member other than the conductor pieces, repeatedly measures time from when the pulsed electromagnetic wave is radiated to when the reflected pulsed electromagnetic wave is received, stores, as a reference value, time at which no distortion occurs on the tire, and compares the measured time with the stored reference value to detect a distortion of the tire.
