The present invention is directed to a pneumatic tire comprising a carcass and an innerliner in direct contact with the carcass, the innerliner comprising: a film comprising a blend of a polyamide, an α-olefin graft copolymer, and an ionomer; and an adhesive layer disposed between the film and the carcass, the adhesive layer comprising: a polymeric amine and a resorcinol-formaldehyde-latex (RFL) adhesive. The invention is further directed to a method of building a pneumatic tire comprising the steps of: exposing an innerliner film to a corona discharge to create a corona treated film, the innerliner film comprising a blend of a polyamide, an α-olefin graft copolymer, and an ionomer; disposing a polymeric amine onto the corona treated film to create an amine treated film; disposing a resorcinol-formaldehyde-latex (RFL) adhesive on the amine treated film to create a treated innerliner film; and incorporating the treated innerliner film into a tire build such that the treated innerliner film is in direct contact with a tire carcass.
