There is provided an inspection method for inspecting an object built on a tire building drum to make up a pneumatic tire with respect to profile thereof in process of production of the tire includes, in which data with respect to a profile of the object for a single rotation of the tire building drum is acquired by a two-dimension laser sensor having a detection range along a lateral direction of the object while rotating the drum. Then, using the data so acquired, a radial run-out (RRO) in a circumferential direction of the tire is averaged out in a lateral direction of the object for harmonic analysis, and whether or not the magnitude of the harmonic obtained as a result of the analysis falls within a predetermined range is determined.
