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).
