Abstract of the Disclosure PNEUMATIC TIRE HAVING A MULTILAYERED INNERLINER The present invention relates to a pneumatic rubber tire having an integral innerliner characterized by being a rubber laminate having at least three layers. At least two of the layers comprise a sulfur cured rubber composition containing, based on 100 parts by weight of rubber, 100 parts of an acrylonitrile/diene copolymer rubber having an acrylonitrile content ranging from about 30 to about 45 percent. The thickness of each acrylonitrile/diene layer ranges from about 25 microns to 380 microns. Interdispersed between the two layers of acrylonitrile/diene copolymer is at least one layer of a sulfur cured rubber selected from the group consisting of natural rubber, halogenated butyl rubber, butyl rubber, cis-1,4-polyisoprene, styrene-butadiene rubber, cis-1,4-polybutadiene, styrene/isoprene/ butadiene rubber or mixtures thereof. The laminate may contain from about 3 to 100 individual layers.
