Claim 16:
17. A tire comprising a mark provided on a surface of a sidewall portion so as to be raised from the surface, wherein
the mark includes a radially upper edge and a radially lower edge,
a curved surface portion, which extends from the radially lower edge to the radially upper edge, is curved so as to project in a direction substantially perpendicular to the surface and has a first side in a first tire circumferential direction and a second side in a second tire circumferential direction opposite the first tire circumferential direction, and
a first flat surface portion connected to and extending laterally from the first side of the curved surface portion that gradually decreases in height from the connection to the first side, which is raised above the height of the sidewall, toward the sidewall surface with increasing distance in the first tire circumferential direction from the curved surface portion,
a second flat surface portion connected with and extending laterally from the second side of the curved surface portion that gradually decreases in height from the connection with the second side, which is raised above the height of the sidewall, toward the sidewall surface with increasing distance in the second tire circumferential direction from the curved surface portion,
wherein, when viewed in a tire axial direction, a first boundary line between the first side of the curved surface portion and the first flat surface portion is a first curved line curve so as to project on the first side of the curved surface portion surface and a second boundary line between the second side of the curved surface portion and the second flat surface portion is a second curved line curved so as to project on the second side of the curved surface portion,
wherein a length in the first tire circumferential direction of the first flat surface portion is smaller than a length in the second tire circumferential direction of the second flat surface portion, and
wherein the length of the length in the first tire circumferential direction of the first flat surface portion is larger than a height of the curved surface portion above the sidewall surface.
