PROBLEM TO BE SOLVED: To provide a bias tire capable of improving durability performance.SOLUTION: A bias tire comprises: a pair of bead cores; the bead fillers disposed outside respective bead cores in a tire radial direction; and a carcass layer which is bridged between the pair of bead cores and whose end part is rewound while wrapping the bead cores and bead fillers to be locked. At any position within a range of 0.9 times or more and 1.6 times or less of flange height of the rim in which the bias tire is mounted in a tire cross section in a tire meridian direction, the curved shape of an innermost cord of the carcass layer in a tire width direction protrudes outside in the tire width direction. Besides, the curved shape of an outermost cord of the carcass layer in the tire width direction protrudes outside in the tire width direction at any position within a range of 1.1 times or more and 1.6 times or less of the flange height in the tire cross section in the tire meridian direction.SELECTED DRAWING: Figure 1

    【課題】耐久性能を向上させることができるバイアスタイヤを提供する。【解決手段】バイアスタイヤは、一対のビードコアと、一対のビードコアそれぞれのタイヤ径方向外側に配置されるビードフィラーと、一対のビードコア間に架け渡されると共にビードコアおよびビードフィラーを包み込みつつ端部が巻き返されて係止されるカーカス層とを備えるバイアスタイヤであり、タイヤ子午線方向の断面で、バイアスタイヤが組込まれるリムのフランジの高さの0.9倍以上1.6倍以下の範囲のいずれかの位置において、カーカス層の最もタイヤ幅方向内側のコードの湾曲形状がタイヤ幅方向の外側に凸であり、かつ、タイヤ子午線方向の断面で、フランジの高さの1.1倍以上1.6倍以下の範囲のいずれかの位置において、カーカス層の最もタイヤ幅方向外側のコードの湾曲形状がタイヤ幅方向の外側に凸である。【選択図】図1
