Methods For Treating Inner Liner Surface, Inner Liners Resulting Therefrom And Tires Containing Such Inner Liners

A method for treating the surface of a cured inner liner comprising:

• providing a cured inner liner having an upper and a lower surface wherein the inner liner comprises rubber a majority by weight of which comprises butyl rubber (optionally halogenated) and the lower surface further comprises polysiloxane moieties, and
• treating the lower surface of the cured inner liner to increase its hydrophilicity by oxidizing at least a portion of the polysiloxane moieties, thereby producing a treated, cured inner liner.

A cured tire comprising:

• a treated, cured inner liner comprising rubber a majority by weight of which comprises butyl rubber (optionally halogenated) and having an upper and a lower surface wherein the lower surface is radially inward facing and further comprises silicon atoms within silanol moieties,
• at least one component radially inner of the inner liner,
• optionally an adhesive layer between the lower surface of the inner liner and the at least one radially inner component.
