Abstract:
An improved method for expanding and curing foamable elastomeric material which is placed within the cavity of a previously molded tire and mounting the tire onto a wheel rim, the method comprising:at least partially filling the cavity of the previously molded tire with foamable elastomeric material; curing the foam filled tire on a curing rim, the curing rim having a reduced friction coated surface; removing the cured tire from the curing rim by slipping the cured tire off the coated surface of the curing rim; wrapping the cured tire for storage and shipment with a protective layer; removing the protective layer; attaching a reduced friction coated insertion cap onto the wheel rim to form a wheel rim and insertion cap assembly, the insertion cap abutting an end of the wheel rim; and inserting the wheel rim and insertion cap assembly into the foam filled tire by pressing the wheel rim and insertion cap assembly against the cured foam filled tire sufficient to slip the tire onto the rim.
