To provide a manufacturing method for a tire that is superior in molding accuracy.SOLUTION: The manufacturing method for a tire includes: a step (A) of winding a strip 20 supplied from an applicator 14 around a former 6 to obtain a wound body; a step (B) of combining the wound body with the other rubber member to form a low cover; and a step (C) of vulcanizing the low cover to obtain a tire from the low cover. In the step (A), a position of the applicator 14 with respect to the former 6 is adjusted based on deviations of the strip 20 with respect to the applicator 14, while making the applicator 14 supply the strip 20 to the former 6.SELECTED DRAWING: Figure 1 【課題】成形精度に優れるタイヤの製造方法の提供。【解決手段】このタイヤの製造方法は、（Ａ）アプリケータ１４から供給されたストリップ２０をフォーマ６に巻回して巻回体を得る工程、（Ｂ）前記巻回体と他のゴム部材とを組み合わせてローカバーを形成する工程及び（Ｃ）前記ローカバーを加硫して前記ローカバーからタイヤを得る工程を含む。前記工程（Ａ）において、アプリケータ１４でストリップ２０をフォーマ６に供給しつつ、アプリケータ１４に対するストリップ２０のずれ量に基づいて、フォーマ６に対するアプリケータ１４の位置が調整される。【選択図】図１
