To provide a method for producing a tire that can effectively prevent sulfur migration to a vulcanization bladder when vulcanizing an unvulcanized tire having a member containing high concentrations of sulfur on the tire inner surface.SOLUTION: A method for producing a tire has a vulcanization step for vulcanizing an unvulcanized tire 20 that has, on at least part of a tire innermost surface 20a, a high-concentration sulfur rubber member that is composed of a rubber composition containing sulfur of 1.0 pt.mass or more relative to a rubber component of 100 pts.mass. In the vulcanization step, used is a vulcanization bladder 10 composed of a bladder rubber composition containing fluorine rubber of 50-100 mass%.SELECTED DRAWING: Figure 1

    【課題】タイヤ内面に硫黄を高濃度に含有する部材を備えた未加硫タイヤを加硫する場合に、加硫用ブラダーへの硫黄の移行を効果的に抑制できる、タイヤの製造方法の提供。【解決手段】ゴム成分100質量部に対して、硫黄を1.0質量部以上含むゴム組成物からなる高濃度硫黄ゴム部材を、タイヤ最内面20aの少なくとも一部に備える未加硫タイヤ20に加硫を行う加硫工程を含み、前記加硫工程では、フッ素ゴムを50〜100質量%含むブラダー用ゴム組成物からなる加硫用ブラダー10を用いるタイヤの製造方法。【選択図】図1
