Abstract
The present invention relates to a pneumatic tire having an inner liner formed from a rubber composition that includes a butyl rubber in which the Mooney viscosity measured at 130° C. of an unvulcanized rubber of the rubber composition 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. The rubber gauge of the tire exhibits improved uniformity and is superior in air permeability resistance.
