ABSTRACT:
A tire distortion detecting method for detecting a detection of the tire during the running of a vehicle, a distortion detector, a sensor unit thereof, and a tire having the same whereby the occurrence of a deterioration can be reduced and applicability is widened to a control system such as a stability control system. Sensor units100are embedded at some intervals in the circumferential direction of the tire. In the sensor unit100, a conductor pattern is changed in shape according to a distortion of a tire300so as to change the resonance frequency of a radiated electromagnetic wave. An electromagnetic wave is radiated from a monitoring device200.An electromagnetic wave radiated from the sensor unit100is compared with a detection result stored when no distortion occurs on the tire300, so that a distortion of the tire300is detected.
