To that end, a base tire is enclosed within a curing mold, the side regions of the base tire are heated by a first heating means, the tread region of the base tire is heated by a second heating means, and a cure-molding is performed such that the amount of heat given to the tread region by the second heating means is smaller than the amount of heat given to the side regions by the first heating means.
