Zusammenfassung:	To reduce incidences of rubber bite appearance defects while increasing formation efficiency of recesses.SOLUTION: The method for manufacturing a tire includes a recess forming step S3 of forming a recess 21 in a region Q facing a boundary 18 on an outer surface of a green tire 1L before charging the green tire 1L to a vulcanizing mold 17. The recess forming step S3 includes a monitoring step S3b for measuring a shape of the recess 21 of the green tire 1L by a profile measuring device 37 during recess formation and monitoring a formation state of the recess 21.SELECTED DRAWING: Figure 4 【課題】凹部の形成効率を高めながら、ゴム噛み外観不良の発生率を減じる。【解決手段】加硫金型１７に生タイヤ１Ｌを投入する前に、生タイヤ１Ｌの外面上の境界線１８に面する領域Ｑに凹部２１を形成する凹部形成工程Ｓ３を含む。凹部形成工程Ｓ３は、凹部形成中の生タイヤ１Ｌの凹部２１の形状をプロファイル測定機３７で測定して、凹部２１の形成状態を監視する監視工程Ｓ３ｂを含む。【選択図】図４
