ABSTRACT:
An inspection method for inspecting beads provided on a tire building drum in process of production a pneumatic tire includes measuring a displacement amount in a radial direction on each of the beads lying axially on both sides of the drum with a distance sensor such as an eddy current sensor while rotating the drum, synthesizing displacement amounts so obtained on the beads on both the sides, calculating a harmonic of the displacement amounts in the radial direction of the beads by performing harmonic analysis on a resultant synthesized displacement amount, and determining whether the magnitude of the harmonic so calculated falls within a predetermined range.
