[PROBLEMS] To provide a rubber composition from which an inner liner improved in good balance between air permeation resistance and flex fatigue resistance and a pneumatic tire using the inner liner. The rubber component is represented by the following general formula (1) (R 1 and R 2 each represents a hydrocarbon group optionally having a hetero atom having 1 to 11 carbon atoms). A rubber composition for an inner liner containing 0.1 to 5.0 parts by mass of a tetrazine-based compound is used. [Chemical 1] [Selection figure] None |
