To provide a tire which has a small rolling resistance and excellent durability, and reduces load on environment.SOLUTION: A tire comprises an organic fiber cord which is treated with an adhesive composition containing polyphenols and aldehydes. In the tire, the organic fiber cord includes semi-aromatic polyamide filament comprising a polycondensate of an aromatic dicarboxylic acid-containing dicarboxylic acid and a non-aromatic diamine or a polycondensate of an aromatic dicarboxylic acid and an aromatic diamine-containing diamine. In this tire, a carcass 5, which toroidally extends between a par of bead parts 1, preferably includes the organic fiber cord, and further, it is also preferable that belt reinforcement layers 7A, 7B, which are located on an outer side in a tire radial direction of a belt 6 located on the tread part 3, include the organic fiber cord.SELECTED DRAWING: Figure 1

    【課題】転がり抵抗が小さく、優れた耐久性を有し、環境への負荷を低減したタイヤを提供する。【解決手段】ポリフェノール類と、アルデヒド類と、を含む接着剤組成物で処理した有機繊維コードを具えるタイヤにおいて、前記有機繊維コードが、芳香族ジカルボン酸を含むジカルボン酸と、非芳香族ジアミンと、の重縮合物、又は、非芳香族ジカルボン酸と、芳香族ジアミンを含むジアミンと、の重縮合物からなる半芳香族ポリアミドのフィラメントを含むことを特徴とする、タイヤである。該タイヤにおいては、一対のビード部1間にトロイド状に延在するカーカス5が、前記有機繊維コードを含むことが好ましく、また、トレッド部3に配置したベルト6のタイヤ半径方向外側に配置したベルト補強層7A,7Bが、前記有機繊維コードを含むことも好ましい。【選択図】図1
