The carcass ply includes a first curvature change portion that is a boundary between a first segment and a second segment and whose curvature is larger than a curvature of the first segment in a cross-section, and a second curvature change portion that is a boundary between the second segment and a third segment and whose curvature is smaller than the curvature of the second segment on the cross section. The tire further includes a cushion rubber whose inner edge is located at the first curvature change portion and that is disposed between the carcass ply and the belt layer.",
