To improve readability of a two-dimensional code by suppressing falling of rubber around a dot hole of the two-dimensional code impressed on a side wall part when a pneumatic tire is used for a long period of time.SOLUTION: A side rubber member of a pneumatic tire, which is long in one direction, constitutes a pair of annular side wall parts by being wound onto the circumference of the tire. Both ends of the side rubber member are provided with inclined end surfaces inclined in the same direction with respect to a thickness direction of the side rubber member. The side wall part comprises a joined part where the inclined end surfaces of the side rubber member are butted to each other and a two-dimensional code. The two-dimensional code is provided at a place separated away in a tire circumferential direction from the joined part.SELECTED DRAWING: Figure 3

    【課題】タイヤの長期使用の際、サイドウォール部に刻印した二次元コードの、ドット孔周りのゴムの欠落を抑制して、二次元コードの読み取りを向上させる。【解決手段】空気入りタイヤのサイドゴム部材は、一方向に長く、タイヤ周上に巻き回して環状の一対のサイドウォール部を構成する。前記サイドゴム部材の両端は、前記サイドゴム部材の厚さ方向に対して同じ向きに傾斜させた傾斜端面を備える。前記サイドウォール部は、前記サイドゴム部材の前記傾斜端面同士を互いに付き合わせた接合部と、二次元コードと、を備える。前記二次元コードは、前記接合部からタイヤ周方向に離間した場所に設けられている。【選択図】図3
