To provide a pneumatic tire manufacturing method that can suppress tire vulcanization failure.SOLUTION: A coating layer 23 for coating a transponder 20 has, in a thickness direction thereof, a front surface layer 23x positioned on a front side of the transponder 20 and a rear surface layer 23y positioned on a rear side of the transponder 20. A step 24 is formed so that end positions of the front surface layer 23x and the rear surface layer 23y are not coincident with each other at at least one end of both ends 23a, 23b of the coating layer 23 in a width direction. The transponder 20 coated with the coating layer 23 having the step 24 is embedded in an unvulcanized tire, and the unvulcanized tire is vulcanized.SELECTED DRAWING: Figure 4 【課題】タイヤの加硫故障を抑制することを可能にした空気入りタイヤの製造方法を提供する。【解決手段】トランスポンダ２０を被覆する被覆層２３がその厚さ方向においてトランスポンダ２０の表面側に位置する表面層２３ｘとトランスポンダ２０の裏面側に位置する裏面層２３ｙとを有し、被覆層２３の幅方向の両端部２３ａ，２３ｂのうち少なくとも一方側の端部において表面層２３ｘと裏面層２３ｙの端部位置が互いに一致しないようにステップ２４を形成し、ステップ２４を有する被覆層２３で被覆されたトランスポンダ２０を未加硫タイヤに埋設し、未加硫タイヤを加硫する。【選択図】図４
