Abstract

A process for retreading a tire, the process comprising the steps of providing a tire casing; providing a cured rubber component having first and second planar surfaces, where the first planar surface includes a tread pattern; providing a cushion gum, wherein the cushion gum is a composition including a functional polymer including at least one functional group, and a crosslinking agent including at least two moieties that will react with the functional group of the functional elastomer; applying the cushion gum to the tire casing; applying the second planar surface of the cured rubber to the cushion gum to form a tire composite; and treating the tire composite to thereby form a retread tire.
