To provide a pneumatic tire capable of suppressing an increase in weight and a deterioration in rolling resistance even if a highly raised convex mark is arranged on a sidewall part.SOLUTION: A raw tire manufacturing method 100 includes: a first step S1 of forming a cylindrical or annular unvulcanized carcass; a second step S2 of winding unvulcanized sidewall rubber around each of a pair of outer peripheral surfaces on an axially outer side of the carcass; and a third step S3 of locally attaching an unvulcanized band-shaped rubber to a portion of the outer peripheral surface of at least one of the sidewall rubbers.SELECTED DRAWING: Figure 3
【課題】隆起高さの高い凸状標章がサイドウォール部に配されていても、重量増と転がり抵抗の悪化を抑制できる空気入りタイヤを提供する。【解決手段】生タイヤ製造方法100は、円筒状または円環状の未加硫のカーカスを形成する第1工程S1と、カーカスの軸方向外側の一対の外周面のそれぞれに、未加硫のサイドウォールゴムを巻付ける第2工程S2と、少なくとも一方のサイドウォールゴムの外周面の一部に未加硫の帯状ゴムを局所的に貼付ける第3工程S3とを含む、【選択図】 図3
