  "textContent": "A mold includes a tread-forming surface to shape a tread surface. The tread-forming surface can include projections to form circumferential grooves, and land surface-forming portions to form land surfaces. Among the three land surface-forming portions aligned in an axial direction with the projections interposed therebetween, the land surface-forming portion located between the two projections can be a curved land surface-forming portion. A contour of the curved land surface-forming portion can be represented by one or more circular arcs. A boundary between a reference side surface of each projection and the curved land surface-forming portion can be a reference boundary point, and the reference boundary point can be located inward of a reference forming surface of the tread-forming surface.",
