<p><P>PROBLEM TO BE SOLVED: To provide a method capable of reducing unevenness of a butyl rubber gauge when it is molded to a tire, and to provide a rubber composition with sufficient air permeation-resistance (air retaining property) improving evenness of the butyl rubber gauge by controlling an unvulcanized rubber characteristic, and to provide a tire having an inner liner comprising the composition. <P>SOLUTION: The pneumatic tire has the inner liner comprising the rubber composition for the pneumatic tire in which Mooney viscosity measured at 130°C of the unvulcanized rubber of the rubber composition for the pneumatic tire containing the butyl rubber is 45 or higher. In the pneumatic tire, an average value and standard deviation of the butyl rubber gauge of a shoulder part of the finished tire satisfy (standard deviation of butyl rubber gauge)/(average value of butyl rubber gauge)≤0.060. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
