A tire mold is provided with a groove-like saw cut in an area of a tire molding surface which comes into contact with a side surface of a tire. The saw cut comprises a pair of circumferential saw cuts arranged to be spaced in a tire diametrical direction, a grid-like saw cut which is expanded between the pair of circumferential saw cuts, and a plurality of frame-like saw cuts which are dotted between the pair of circumferential saw cuts. The frame-like saw cuts fringe a closed area which is wider than a smooth area defined by the grid-like saw cut. The grid-like saw cut surrounds the frame-like saw cuts to prevent the frame-like saw cuts from coming into contact with each other. The frame-like saw cuts are coupled to each other via the grid-like saw cut.
