Abstract: A uniformity waveform for a tire (T) and a rotational phase of a load drum (4) are measured with a load drum (4) pressed against the tire (T). In a waveform of the frequency domain acquired by frequency conversion of the uniformity waveform, the amplitude and phase for a component of an integer multiple of the rotational frequency of the load drum (4) are found and stored as a correction parameter. A corrected tire (T) uniformity waveform is calculated by subtracting from the uniformity waveform a correction waveform calculated on the basis of the correction parameter, the correction waveform being the one in the rotational phase range of the load drum (4) during tire measurement.
