Abstract: A pneumatic tire formed by using a rubber composition comprising a vulcanization accelerator represented by the following general formula: wherein R represents a hydrogen atom, an alkyl group, or an aryl group, and R represents an alkyl group or an aryl group when R represents a hydrogen atom, and represents a hydrogen atom, an alkyl group, or an aryl group when R represents an alkyl group or an aryl group, in an amount of 0.2 to 8.0 parts by weight per 100 parts by weight of a rubber component. A pneumatic tire which maintains low rolling resistance and is improved to prevent resistance to ply-end separation throughout the entire term of tire use, a pneumatic tire which shows excellent controllability and durability in the last stage of tire use, and a pneumatic tire which prevents heat aging of belt layers and a decrease in the adhesion of steel cord with a rubber composition and shows excellent durability are provided.

Abstract: The rubber composition of the present invention is used for producing an inner liner of a pneumatic tire, and is obtained by compounding a rubber component and a layered or plate-like mineral. The layered or plate-like mineral has an aspect ratio of 3 or more and less than 30. The present invention further provides a production method of the rubber composition and a pneumatic tire which is produced by using the rubber composition. The present invention is applicable to a tire of passenger vehicles, bus or truck, and a tire of airplane. According to the present invention, the air permeation resistance is remarkably improved and the workability is also improved. Therefore, the rapture and hole defect of a non-vulcanized sheet during the tire construction can be avoided. By using the rubber composition, the gauge of the inner liner of pneumatic tire can be reduced while maintaining the inner pressure of tire, thereby reducing the weight of tire.

Abstract: A rubber composition for the inner liners of pneumatic tires which comprises a rubber ingredient and a lamellar or flaky mineral having an aspect ratio of 3 to 30, excluding 30; a process for producing the rubber composition; and a pneumatic tire made with the rubber composition. The composition is applicable to tires for automobiles, buses, motor trucks, and aircraft. The composition has significantly improved impermeability to air and improved processability. During tire production, an unvulcanized sheet thereof is less apt to break or come to have holes. The pneumatic tire produced with the rubber composition as an inner liner rubber can have a reduced weight because the inner liner can have a reduced gauge while maintaining an internal pressure of the tire.
