PROBLEM TO BE SOLVED: To provide a tubeless tire with durability improved by having reinforcing means to effectively reduce stress applied to a portion contacting a rim flange portion and to a carcass edge portion.SOLUTION: A tubeless tire comprises: a steel chafer 140 wound around the outside of a carcass 120; a nylon chafer 150 wound around the outside of the steel chafer 140; a first reinforcing rubber layer 160 disposed between a bead core 110 and the carcass 120; and a second reinforcing rubber layer 170 disposed between the steel chafer 140 and the nylon chafer 150.EFFECT: In this configuration, the bead portion is improved in durability under a high-pneumatic-pressure condition by reducing the stress applied to interfaces between the carcass edge, the steel chafer 140 and the nylon chafer 150.SELECTED DRAWING: Figure 2

    【課題】リムフランジ部に当接する部位とカーカスエッジ部の応力を効果的に低減する補強手段を設けることにより、耐久性の向上したチューブレスタイヤの提供。【解決手段】カーカス120の外側にはスチールチェーファ140を巻き込むように配置し、スチールチェーファ140の外側にナイロンチェーファ150を巻き込むように配置し、ビードコア110とカーカス120の間に第1の補強ゴム層160を配置し、スチールチェーファ140とナイロンチェーファ150の間に第2の補強ゴム層170を配置したチューブレスタイヤ。【効果】この構成により、カーカスエッジと、スチールチェーファ140とナイロンチェーファ150の界面応力を減らして高い空気圧使用条件でビード部の耐久性を高めることができる。【選択図】図2
