PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in uniformity and productivity.SOLUTION: A tire 7 is configured so that, a band 16 is formed by winding a first ribbon 32, a second ribbon 34, and a third ribbon 36. Each of the first ribbon 32, the second ribbon 34, and the third ribbon 36 has a cord extending in a longitudinal direction. One axial outside area on an equator CL of the tire 7 is a first area A1, the other axial outside area on the equator CL is a second area A2, and at this time, in the first area A1, the first ribbon 32 is spirally wound in a substantially peripheral direction, from inside to outside of the axial direction. In the second area A2, the second ribbon 34 is spirally wound in a substantially peripheral direction from inside to outside of the axial direction. On the equator CL, the third ribbon 36 is wound in the peripheral direction.SELECTED DRAWING: Figure 2 【課題】ユニフォミティ及び生産性に優れる空気入りタイヤの提供。【解決手段】このタイヤ７では、バンド１６は、第一リボン３２と第二リボン３４と第三リボン３６とを巻回すことで構成されている。第一リボン３２、第二リボン３４及び第三リボン３６のそれぞれは、長さ方向に延在するコードを備えている。上記タイヤ７における赤道面ＣＬの一方の軸方向外側の領域が第一領域Ａ１とされ、赤道面ＣＬのもう一方の軸方向外側の領域が第二領域Ａ２とされたとき、第一領域Ａ１において、第一リボン３２は軸方向内側から外側に向けて略周方向に螺旋状に巻回されている。第二領域Ａ２において、第二リボン３４は軸方向内側から外側に向けて略周方向に螺旋状に巻回されている。赤道面ＣＬ上において、第三リボン３６は周方向に巻回されている。【選択図】図２
