The invention provides a tire for an automatic two-wheeled vehicle. The tire for the automatic two-wheeled vehicle improves rim deviation prevention performance and steering stability while maintaining rim assembly performance. A tire for an automatic two-wheeled vehicle includes a pair of bead portions (4) in which bead cores (5) are embedded. The pair of bead portions (4) includes a rim contact surface (10). The rim contact surface (10) includes a bead bottom surface (11), a bead side surface (12), and a bead heel surface (13). In an imaginary rim assembly state, the diameter of an intersection point between an imaginary first straight line (16) in which the bead bottom surface (11) extends outward in the axial direction of the tire and an imaginary second straight line (17) in which the bead side surface (12) extends inward in the radial direction of the tire is 99.0-99.6% of the rim diameter of a normal rim (R).

    本发明提供自动二轮车用轮胎,其在维持轮辋组装性能的同时提高轮辋偏移防止性能及操纵稳定性。自动二轮车用轮胎包含分别埋设有胎圈芯(5)的一对胎圈部(4)。一对胎圈部(4)包含轮辋接触面(10)。轮辋接触面(10)包含胎圈底面(11)、胎圈侧面(12)以及胎圈胎踵面(13)。在假想轮辋组装状态下,胎圈底面(11)向轮胎轴向外侧延长的假想的第1直线(16)与胎圈侧面(12)向轮胎半径方向内侧延长的假想的第2直线(17)的交点的直径为正规轮辋(R)的轮辋直径的99.0%~99.6%。
