Summary:The present invention relates to a pneumatic tire having a layer, preferably an innerliner, for prevention, or retardation, of air/moisture vapor permeation from its inner chamber into the remainder of the tire. The innerliner is an isobutylene copolymer elastomer-based composition which contains a dispersion of carbon black and precipitated silica reinforcement together with a coupling agent. In one aspect, the coupling agent is a bis(3-triethoxysilylpropyl) polysulfide which contains an average of from 2 to 4, preferably from 2 to 2.6, connecting sulfur atoms in its polysulfidic bridge. In another aspect, the coupling agent is blended with the composition in a productive mixing stage.
