The invention provides a tire (2) capable of preventing a protrusion from being engaged when the tire is assembled on a rim. A tire (2) is provided with a bead section (2B) fitted to a rim (R). The bead section (2B) is provided with: a first exhaust line (50) extending in the circumferential direction; a second exhaust line (52) positioned on the outside of the first exhaust line (50) and extending in the circumferential direction; a cylindrical protrusion (54) positioned on the outside of the second exhaust line (52); and a saw mark (56) spanning between the first exhaust line (50) and the cylindrical protrusion (54) and intersecting the second exhaust line (52). The first exhaust line (50), the second exhaust line (52), the cylindrical protrusion (54), and the saw mark (56) protrude from the outer surface of the bead portion (2B). The second exhaust line (52) is positioned closer to the cylindrical projection (54) than an intermediate position (LC) between the first exhaust line (50) and the cylindrical projection (54).
本发明提供能够防止在组装于轮辋时突出物啮入的轮胎(2)。轮胎(2)具备嵌合于轮辋(R)的胎圈部(2B)。胎圈部(2B)具备:沿周向延伸的第一排气线(50)、位于第一排气线(50)的外侧并沿周向延伸的第二排气线(52)、位于第二排气线(52)的外侧的圆柱状突起(54)、以及架设于第一排气线(50)与圆柱状突起(54)之间并与第二排气线(52)交叉的锯痕(56)。第一排气线(50)、第二排气线(52)、圆柱状突起(54)以及锯痕(56)从胎圈部(2B)的外表面突出。第二排气线(52)位于比第一排气线(50)与圆柱状突起(54)之间的中间位置(LC)靠圆柱状突起(54)侧的位置。
