Patent ID: 8034267

Claim:
A method of producing a composite solid tire, comprising the steps of providing a rubber layer to be an inner layer of said tire; applying a primer and an adhesive to the outer circumferential surface of said rubber layer; providing a die-casting device including an outer die having a cylindrical shape with a bottom; pre-heating the outer die and the rubber layer individually, the outer die being heated to a temperature of 100° C. to 110° C. and the rubber layer being heated to a temperature 5° C. higher than that of the pre-heated outer die; setting the pre-heated rubber layer and the preheated outer die concentrically such that a casting space is formed between an inner circumferential surface of the outer die and the outer circumferential surface of the rubber layer; and introducing raw materials of a thermo-setting polyurethane elastomer into the casting space to react and cure, thereby integrally forming an outer layer of the thermo-setting polyurethane elastomer.
