Method of curing foam inflated tires and an improved rim

Abstract

A method for expanding and curing formable elastomeric material 2, which is placed in the cavity 14 of a previously molded tire 10, is disclosed. The tire 10 when filled with foamable rubber material 2 is mounted on a curing rim 20 and contacted with heat to simultaneously foam and cure the elastomeric material 2 within the tire cavity 14. The curing rim 20 has a finished or a coated surface 30 that permits the cured foam filled tire 10 to be removed after curing by slipping the cured tire 10 off the coated surface 30 of the curing rim 20.

1 . An improved method for expanding and curing foamable elastomeric material which is placed within the cavity of a previously molded tire, the method comprising: 
 at least partially filling the cavity or the previously molded tire with foamable elastomeric material;    curing the foam filled tire on a curing rim, the curing rim having a coated surface; and    removing the cured tire from the curing rim by slipping the cured tire off the coated surface of the curing rim.    
     
     
         2 . The improved method of claim further comprising: 
 wrapping the cured tire for storage and shipment with a protective layer.    
     
     
         3 . The improved method further comprising: 
 removing the protection layer attaching a coated insertion cap onto the wheel rim abutting of end of the wheel rim;    inserting the capped wheel rim assembly into the foam filled tire, pressing the capped wheel rim assembly against the cured foam filled tire sufficient to slip onto the rim.    
     
     
         4 . A rim for curing a previously molded tire with a foamable elastomeric material; the rim comprising: 
 an exterior surface, the exterior surface having a coated surface for slipping the cured tire from the rim.    
     
     
         5 . The rim for curing a previously molded tire with a foamable elastomeric material of  claim 5 , wherein the coated surface is coated with a material selected from the group including; baked on Teflon™, baked on coatings, McLube 1711L, waterless Pam grill spray.
