PROBLEM TO BE SOLVED: To suppress increase of rolling resistance, and reduce ambient noise without affecting to formation of a carcass line.SOLUTION: A pneumatic tire 10 comprises a carcass 13, peripheral belt 16, and inner liner 18. The peripheral belt 16 is formed of at least one layer of peripheral belt layer. The peripheral belt layer has a cord extending along the tire peripheral direction. Thickness of the inner liner 18 on at least part of a side part 19 is 1.5 mm or more. When a young modulus of the cord of the peripheral belt layer is Y (GPa), and a layer number of the peripheral belt is m, and a number of implantation of the cord per 50 mm, and X=Y×m×n is defined, X is 750 or more. |
