PROBLEM TO BE SOLVED: To provide a pneumatic tire manufacturing method in which a low cover can be molded to dispense with or minimize stitch down of an SOT structure; and to provide a pneumatic tire.SOLUTION: A pneumatic tire manufacturing method includes: a step of sticking side walls 34a and 34b, an inner 32, and a ply 35 together on a first molding drum, setting a pair of beads 36a and 36b, forming a tread side part 13b on the side walls, and molding a first cover 38; a step of sticking a breaker 22 and a band together on a second molding drum, forming a tread central part 10 on the band, and molding a tread ring; a step of inserting the first cover inside the tread ring, and inflating the first cover to crimp the tread ring and the first cover; and a step of folding the side walls back toward the side surface of the inflated first cover, sticking them to the side surface of the first cover, and sticking a tread side part and a tread central part together.SELECTED DRAWING: Figure 4

    【課題】SOT構造のステッチダウンを不要、最少限にしてローカバーの成形を行うことができる空気入りタイヤの製造方法および空気入りタイヤを提供する。【解決手段】1st成形ドラム上にサイドウォ−ル34a,b、インナー32、プライ35を貼り付け、1対のビード36a,bをセットし、サイドウォ−ル上にトレッド側辺部13bを形成して1stカバー38を成形する工程と、2nd成形ドラム上にブレーカー22、バンドを貼り重ね、バンド上にトレッド中央部10を形成してトレッドリングを成形する工程と、トレッドリングの内側に1stカバーを挿入して1stカバーを膨らませることによりトレッドリングと1stカバーとを圧着する工程と、サイドウォールを膨らんだ1stカバーの側面に向けて折り返して1stカバーの側面に貼り付けると共に、トレッド側辺部とトレッド中央部とを貼り合わせる工程とを備えている空気入りタイヤの製造方法。【選択図】図4
