In a case where, of the two projections, one projection is a wide projection and the other projection is a narrow projection, when a surface that has a contour represented by at least one circular arc and that is tangent to at least three land surface-forming portions is defined as a reference surface of the tread-forming surface, a drop distance from the reference surface to an end on the wide projection side of the land surface-forming portion is longer than a drop distance from the reference surface to an end on the narrow projection side of the land surface-forming portion.",
