PROBLEM TO BE SOLVED: To provide a tire uniformity measuring method and a measuring apparatus capable of excluding errors and highly precisely identifying AVV characteristic waveforms. SOLUTION: F is a tire axis measurement waveform within the tire phase rangeΣof one circumference of a tire, and K is a drum axis measurement waveform within a drum phase rangeΨcorresponding to the tire phase rangeΣas a contact range between circumferential surfaces. A tire AVV characteristic waveform X is identified by substituting the waveforms F and K; a tire axis AVV error waveform G which is previously identified and which appears independently of tires; and a drum axis AVV error waveform H in the expression (1) (wherein R is a tire/drum radius ratio (the ratio of the rolling radius of the tire to the radius of a loading drum)).
