ABSTRACT:
Separable upper and lower rims of a post-cure tire inflator requiring no upper rim replacing operation which requires much time and labor especially when mounting the upper rim, and also no time and labor for holding a lower rim upward when mounting. In the upper and lower rim for holding the bead section of the tire, a high-pressure air is filled in a cured tire discharged from a tire curing press to thereby inflate and cool the tire; therefore at least the upper rim has stairway-like steps having two or more outer diameters fit to the bead diameters of tires of different sizes and formed by extending a small outer diameter on a large outer diameter.
