A tire mold and tire reduce manufacturing and facilities costs and improve appearance of a product tire. The tire mold includes a tread molding body that molds a tread surface of a tire and is formed by pieces aligned in a circumferential direction of the mold. The tread molding body includes, on a mold face thereof, groove forming protrusions that form grooves on the tread surface and land forming recesses that form land portions on the tread surface and are surrounded by the groove forming protrusions. In a development view in which the pieces are connected, an air release gap in communication with the mold face of the pieces is provided along a boundary line between the pieces. At least one boundary line cuts across a plurality of the land forming recesses. Each boundary line extends through a bend, and the bend is positioned in the groove forming protrusions. |
