ABSTRACT:
A method and means of curing a solid rubber vehicle tire in which a mass of uncured rubber is attached to the outside of a rim, the rim placed in a mold, and heat applied to the rim causing heat to permeate outward through the rubber, producing a gradient of hardness wherein maximum hardness occurs in the rubber adjacent to the rim and thus where the rubber adheres to the rim. This is accomplished by means of two plates which form, with the rim, a sealed cavity interior of the rim to which cavity steam is applied.
