A tire mold used for producing a tire including a tread having a tread surface that comes into contact with a road surface, at least two circumferential grooves (42, 42s, 42m, 42w, 42n) having a groove width of not less than 9 mm being formed on the tread so as to extend in a circumferential direction, thereby forming at least three land portions (44, 44s, 44m) in the tread, the tread surface including the at least two circumferential grooves (42, 42s, 42m, 42w, 42n) and at least three land surfaces (46, 46s, 46m) that are outer surfaces of the at least three land portions (44, 44s, 44m), the tire mold comprising: a tread-forming surface for shaping the tread surface, wherein the tread-forming surface includes at least two projections (66, 66s, 66m, 66w, 66n) for forming the at least two circumferential grooves (42, 42s, 42m, 42w, 42n), and at least three land surface-forming portions (68, 68s, 68m) for forming the at least three land surfaces (46, 46s, 46m), characterized in that a contour of a land surface-forming portion (68, 68m) located between two projections (66, 66s, 66m, 66w, 66n) among the at least three land surface-forming portions (68, 68s, 68m) is represented by a single circular arc that is convex outward, wherein, of the two projections (66, 66s, 66m, 66w, 66n), one projection is a wide projection having a larger width than the other projection, and the other projection is a narrow projection having a smaller width than the one projection, and a wide-side drop distance MDW that is a distance from a reference surface of the tread-forming surface to an end (Pfw) on the wide projection side of the land surface-forming portion (68, 68m) is longer than a narrow-side drop distance MDN that is a distance from the reference surface of the tread-forming surface to an end (Pfn) on the narrow projection side of the land surface-forming portion (68, 68m), wherein the reference surface of the tread-forming surface is defined as a surface that has a contour represented by at least one circular arc and that is tangent to the at least three land surface-forming portions (68, 68s, 68m). a tread-forming surface for shaping the tread surface, wherein the tread-forming surface includes at least two projections (66, 66s, 66m, 66w, 66n) for forming the at least two circumferential grooves (42, 42s, 42m, 42w, 42n), and at least three land surface-forming portions (68, 68s, 68m) for forming the at least three land surfaces (46, 46s, 46m), characterized in that a contour of a land surface-forming portion (68, 68m) located between two projections (66, 66s, 66m, 66w, 66n) among the at least three land surface-forming portions (68, 68s, 68m) is represented by a single circular arc that is convex outward, wherein, of the two projections (66, 66s, 66m, 66w, 66n), one projection is a wide projection having a larger width than the other projection, and the other projection is a narrow projection having a smaller width than the one projection, and a wide-side drop distance MDW that is a distance from a reference surface of the tread-forming surface to an end (Pfw) on the wide projection side of the land surface-forming portion (68, 68m) is longer than a narrow-side drop distance MDN that is a distance from the reference surface of the tread-forming surface to an end (Pfn) on the narrow projection side of the land surface-forming portion (68, 68m), wherein the reference surface of the tread-forming surface is defined as a surface that has a contour represented by at least one circular arc and that is tangent to the at least three land surface-forming portions (68, 68s, 68m).
