PROBLEM TO BE SOLVED: To ensure the smooth draw-out of respective segments even if the maximum inner surface width of each of the side wall parts of a product tire becomes far larger than the minimum inner surface width of a bead part. SOLUTION: This tire manufacturing core is equipped with a plurality of segments 2 and 3 and a pair of the rings 5, which is locked with a combination structure 4 for arranging the segments 2 and 3 in an annular form from both sides in the axial direction thereof to hold a plurality of the segments 2 and 3 to a combined posture, to prescribe the inner surface of the tire during the period from the molding of the tire to the completion of the vulcanization of the tire. The respective segments 2 and 3 are constituted so as to be detachably divided into center parts 2a and 3a corresponding to the center part in the width direction of the tire and respective side parts 2b and 3b corresponding to both side parts in the width direction of the tire.
