A mold 56 includes a tread-forming surface 64 for shaping a tread surface 22. The tread-forming surface 64 includes projections 74 for forming circumferential grooves 42, and land surface-forming portions 76 for forming land surfaces 46. Among the three land surface-forming portions 76 aligned in an axial direction with the projections 74 interposed therebetween, the land surface-forming portion 76 located between the two projections 74 is a curved land surface-forming portion 76B. A contour of the curved land surface-forming portion 76B is represented by one or more circular arcs. A boundary between a reference side surface 80a of each projection 74 and the curved land surface-forming portion 76B is a reference boundary point BBm, and the reference boundary point BBm is located inward of a reference forming surface FBL of the tread-forming surface 64.
