To improve the reliability of automobile tires and anti-lock braking system (ABS), smart tires that measure strain of tires are increasingly demanded. The high stiffness of an embedded sensor like a strain gage, however, causes debonding of sensors from tire rubber. In a previous study, the authors proposed a tire strain monitoring method that adopts the tire itself as a sensor with a tuning circuit. Since the deformation of a rectangular specimen used, however, is different from that of an actual tire, the tuning frequency does not change linearly with the strain change of an actual tire. In the present study, the monitoring system with a tuning circuit is applied to an actual radial tire using spectral features of peak spectrum and quality factor as well as tuning frequency to improve the accuracy of strain estimation. As a result, the method is experimentally proved to be effective for the passive wireless strain monitoring of actual radial tires.
