Abstract:
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 to a contact point 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 to a maximum width position is equal to or greater than −10 mm and equal to or less than 10 mm.
