PROBLEM TO BE SOLVED: To provide a vulcanization conditions evaluating method of a pneumatic tire which can reduce labor, time and cost required to evaluate the vulcanization conditions and also reduce refuses. SOLUTION: The vulcanization conditions evaluating method of a pneumatic tire uses a mold comprising a plurality of sectors 1 for molding the tire tread part. By combining simultaneously at least two kinds of sectors different in the groove molding patterns from each other, the pneumatic tire is vulcanized, and, based on the vulcanized state of the part corresponding to each sector of the vulcanized tire, the vulcanization conditions of every sector are evaluated.
