    Abstract: A solid tire mold includes upper and lower pneumatic tire molds. The pneumatic tire molds have adapter receiving surfaces disposed radially inwardly. The pneumatic tire molds are joined at the pneumatic mold receiving portions. The pneumatic tire molds form tread molding surfaces and at least a portion of the shoulder molding surfaces. The solid tire mold also includes toroidal adapters, each having an annular pneumatic mold receiving surface, an annular solid tire curing surface, and a toroidal flange. The flange extends axially inwardly from the lateral wall toward an inner end. The inner end of the flange can be tapered. A toroidal rim extends laterally from one toroidal adapter to the other. The rim is disposed radially outwardly from the toroidal flanges in the assembled solid tire mold.
