PROBLEM TO BE SOLVED: To provide a pneumatic tire having improved durability of a bead part. SOLUTION: This pneumatic tire comprises a carcass 2 formed of a ply that is folded and locked at a bead core 10 of the bead part 1 from a tread part beyond a side wall part and an inner liner 3 that is disposed on a tire bore surface and formed of rubber hardly permeating air. The inner end Ip of the inner liner 3 is lies radially inwardly than the bead core 10, and positions in a region between a radial line passing through the most inner point Bi in the tire axis direction of the bead core 10 and a radial line passing through the intermediate point Bc in the tire axial direction between the most inner point Bi and the most outer point Bo in the tire axis direction Thickness T of the inner liner 3 on a line L passing through the most inner point Bi and the most outer point Bo of the bead core 10 is set at 0.5 mm to 2.0 mm.
