ABSTRACT:
In a tire molding process, a mutual positional deviation or angular deviation between the axis of a carcass member and the axis of a bead core takes place in a produced tire when the bead core is set on the outer periphery of cylindrical carcass member. By the use of an estimation formula for estimating the primary harmonic component in the waveform of a radial force, an inverse waveform with the primary harmonic component inversed is found with respect to the measurement waveform of the produced tire or with respect to the treatment waveform with a numerical value treatment applied thereto. Thereafter, in producing a tire of the same size by the mold used for producing the preceding tire, the mutual positional deviation or angular deviation between the axis of the carcass member and the axis of the bead core found by a backward calculation from the estimation formula is changed to set the bead core on the carcass member.
