It is the purpose of the present invention to provide a rubber composition improving the uniformity of a butyl rubber gauge and being superior in air permeability resistance (air retaining property), when a tire is molded, by a procedure capable of reducing the fluctuation of the butyl rubber gauge, namely, controlling the property of an unvulcanized rubber, and a tire having the inner liner comprising it. The present invention relates to a pneumatic tire having an inner liner comprising a rubber composition for a pneumatic tire in which the Mooney viscosity measured at 130° C. of an unvulcanized rubber of the rubber composition for a pneumatic tire comprising a butyl rubber is at least 45, wherein the average value and standard deviation of the butyl rubber gauge of shoulder portion of a finished tire satisfy: (Standard Deviation of Butyl Rubber Gauge)/(Average value of butyl rubber gauge)≦̸0.060.
