At least one dynamic condition of a pneumatic tire (304, 604, 804, 904, 1004) of a vehicle (802, 1002) is monitored with a transponder (302, 602, 806, 1020) mounted in the tire by sensing (520, 820) fluctuations in coupling of power provided to the transponder form an interrogator (808, 1030). The fluctuations in coupling can provide an indication of dynamic conditions such as tire angular position, rotational velocity and acceleration, steering angle, lateral acceleration, and radial runout. Alternatively, fluctuations in coupling of a signal from the transponder to the interrogator can be sensed to provide an indication of dynamic conditions associated with the pneumatic tire. |
