To improve a lightweight property, low rolling resistance and durability in an actual travel and an aging effect by including a specific quantity of a specific vulcanization accelerator in at least one kind of case rubber to form an inner liner arranged in direct contact with the inner side face of a carcass layer.

This pneumatic tire is provided with a carcass layer extending astride a pair of bead sections and a tread section located on the crown section of the carcass layer, and an inner liner layer is formed on the inner side face of the carcass layer. The inner liner has the gauge of 0.1-0.6 mm, and it contains a vulcanization accelerator expressed by the formula I or II in one kind of case rubber selected from coating rubber for a carcass ply, coating rubber for a belt play and a bead filler at the ratio of 0.5-5.0 pts.wt. against the raw material rubber 100 pts.wt., where R1, R2 indicate each hydrogen atom, alkyl group or aryl group.
