PROBLEM TO BE SOLVED: To provide a tire uniformity measuring apparatus which can detect abnormalities in measuring conditions without newly providing a detector or the like for monitoring the measuring conditions. SOLUTION: A plurality of uniformity values successively measured in a predetermined circumferential range (a rotation angle of 360 degrees) in the tire circumferential direction of a tire to be measured 1 are measured in different rounds (the first and second rounds) of the rotating tire to be measured 1. A calculation section 34 calculates the difference in area (the difference in integral) between a first waveform obtained from a plurality of uniformity values successively measured in the first round and a second waveform obtained from a plurality of uniformity values successively measured in the second round. An abnormality decision section 35 compares the difference in area with a predetermined standard value and decides that there are abnormalities in the measuring conditions when the difference in area exceeds the standard value.
