A method for treating a cured inner liner for a tire comprising:
- a. providing a cured inner liner comprising rubber, a majority of which comprises butyl rubber (optionally halogenated), wherein the cured inner liner has an upper and a lower surface,
- b. treating the lower surface of the cured inner liner with a rubber-containing liquid wherein the rubber-containing liquid comprises at least one conjugated diene monomer-containing rubber, polyurethane and at least one solvent, and
- c. allowing the rubber-containing liquid to dry upon the treated surface of the cured inner liner, thereby producing a rubber-containing film upon the dried, treated surface.
