PROBLEM TO BE SOLVED: To provide a method which makes it possible to efficiently produce a pneumatic tire comprising a tire member that is excellent in low heat build-up properties, and also provide a method which makes it possible to efficiently produce a tire member that is excellent in low heat build-up properties.SOLUTION: A green tire that comprises an unvulcanized member comprising a rubber composition comprising an ionic liquid is vulcanized at 100-140°C, thus efficiently producing a pneumatic tire comprising a tire member that is excellent in low heat build-up properties. An unvulcanized member that comprises a rubber composition comprising an ionic liquid is vulcanized at 100-140°C, thus efficiently producing a tire member that is excellent in low heat build-up properties.SELECTED DRAWING: Figure 1 【課題】第１の課題は、低発熱性に優れたタイヤ部材を備える空気入りタイヤを効率よく製造できる方法を提供することである。第２の課題は、低発熱性に優れたタイヤ部材を効率よく製造できる方法を提供することである。【解決手段】イオン液体を含むゴム組成物を含む未加硫部材を備える生タイヤを１００〜１４０℃で加硫することにより、低発熱性に優れたタイヤ部材を備える空気入りタイヤを効率よく製造する。また、イオン液体を含むゴム組成物を含む未加硫部材を１００〜１４０℃で加硫することにより、低発熱性に優れたタイヤ部材を効率よく製造する。【選択図】図１
