In a tire (2), a contour of an outer surface of the second apex (38) includes: a circular arc (C2) that extends inward from an outer end, in the radial direction, of the contour and is convex outward in the axial direction; and a circular arc (C3) that is located inward of the circular arc (C2) in the radial direction, is in contact with the circular arc (C2), and is convex inward in the axial direction. A difference (Ht-Hw/2) between a height Ht from a bead base line (BBL) to a contact point (Pt) between the circular arc (C2) and the circular arc (C3) and a height that is half of a height Hw from the bead base line (BBL) to a maximum width position is equal to or greater than -10 mm and equal to or less than 10 mm. |
