摘要： A tubular tire for bicycle, automobile and the like, having a tubular cross section and comprising a tread portion, side portions and a bottom portion, is manufactured by molding a base tire composed of the side portions and the bottom portion from a fluidizable high polymer material by means of a split mold assembly and then molding the tread portion and hence a tire product from a fluidizable high polymer material by means of a centrifugal molding machine. The split mold assembly comprises a core having an outer peripheral surface coincident with an inner profile of the base tire and separable mold members having an inner peripheral surface coincident with an outer profile of the base tire.
