Abstract
A tire mold featuring a reusable base mold even when a pattern mold having been fitted to the base mold is to be replaced with another pattern mold. To that end, the tire mold includes a base mold and a pattern mold detachably fitted to the base mold. A tread pattern is formed on a crown region of a tire by a pattern molding surface of the pattern mold which faces the crown region. The base mold has an inner fitting periphery to be fitted to an outer fitting periphery of the pattern mold on the opposite side of the pattern molding surface thereof, and a peripheral length of the inner fitting periphery of the base mold is set shorter than a peripheral length of the outer fitting periphery of the pattern mold.
