A tire shape inspection method executes the following steps: first, as a teaching operation step, boundary lines of the bulge and dent marks are detected in a sample source image of a sample tire, a mask image is generated which denotes the boundary lines, regions are removed from the sample source image which correspond to the boundary lines which are denoted in the mask image, and a height offset image is generated which represents the heights of the remaining regions with one or more offset values. Next, as an inspection operation step, the height offset image is subtracted from an inspection image of the inspection tire, the boundary regions which the mask image represents are removed, and, on the basis of the obtained bulge/dent removal image, shape defects of the sidewall surfaces of the inspection tire are inspected.
