ABSTRACT:
The tire comprises a preformed carcass having a plurality of precured lugs secured to its circumferential surface by a thick layer-like mass of readily cured cushion gum material. The carcass may be of new construction but would usually be obtained by buffing the circumferential surface of a used and worn lugged tire to render the same substantially smooth and even. The lugs are separately formed by simultaneously molding and precuring retread rubber under high pressure and uniformly-applied heat, so as to possess high strength, density and cut and abrasion-resistance. The carcass, cushion gum and lugs are cemented and stitched together at ambient temperature and in a manner minimizing oxidation at their confronting surfaces. When the circumferential surface of the tire carcass to which the lugs are secured possesses a significant curvature in the width direction thereof, the exterior surfaces of the lugs may be and preferably are provided with stress-relieving grooves in their outer surfaces. The aforesaid assembly is then heated within a steam chamber under differential-pressure conditions for only the limited time necessary to vulcanize the cushion gum material and thereby permanently unite the components.
