Abstract
In a tire uniformity measurement, accurate tire uniformity is obtained from a measurement waveform immediately after a rotation of a tire is switched from a normal rotation direction to a reverse rotation direction. A tire uniformity testing device of the present invention includes a measurement unitthat obtains a force variation from a uniformity waveform corrected by a correction unitthat corrects the uniformity waveform so as to eliminate a shift gradient α existing in the uniformity waveform measured after a rotation of a tire Tis reversed, and further includes an air-outflow regulation memberthat regulates an from flowing into a tire Twhen a drumretreats or advances.
