Abstract
The present invention provides a tire distortion detecting method, a distortion detector, and a tire which can reduce the occurrence of a deterioration and can be used for a control system such as a stability control system. That is, series of conductors composed of a plurality of conductor piecesandare provided in two different layers. The conductor piecesandare embedded in lines at predetermined intervals in the circumferential direction of a tire. A pulsed electromagnetic wave is radiated to the surfaces of metal foilsandin the layers from a monitoring deviceprovided in a tire houseof a vehicle. The monitoring devicereceives a pulsed electromagnetic wave reflected from the metal foilsandin the layers or a member other than the metal foils. Time from the radiation of a pulsed electromagnetic wave to the reception of a reflected pulsed magnetic wave is measured repeatedly, time at which no distortion occurs on the tireis stored as a reference value, and the measured time and the stored reference value are compared with each other to detect a distortion of the tire
