PROBLEM TO BE SOLVED: To provide a pneumatic tire which has excellent air permeation resistance and elongation at break and of which the low-temperature embrittlement is suppressed.SOLUTION: On an inner surface of a pneumatic tire, an inner liner 9 to prevent air filled in the tire from leaking out to the outside of the tire is provided. A rubber composition formed by compounding 30 to 70 pts.mass of carbon black with 25 to 50 g/kg of iodine absorption (IA) and 0.1 to 10 pts.mass of lecithin with 100 pts.mass of rubber including 50 to 100 pts.mass of butyl rubber is used for the inner liner 9. |
