A pneumatic tire, comprising: an overlap splice portion in which an inner liner configured from a film whose main component is a thermoplastic resin is adhered to an inner side of a carcass layer of a tire via a tie rubber sheet and end portions in a tire circumferential direction (X-X) of the film overlap via a tie rubber across a tire width direction (E-E), the pneumatic tire satisfying the requirements of: (a) a surface (2A0) on a tire outer circumferential side of the film (2, 2A) positioned on the tire cavity side in the overlap splice portion being formed flat between the overlap splice portion and the portions other than the overlap splice portion; and (b) a surface on a tire cavity side and a surface on a tire outer circumferential side (2B0) of a film (2, 2B) positioned on a tire outer circumferential side in the overlap splice portion being formed flat between the overlap splice portion and the portions other than the overlap splice portion characterized in that the tire further satisfies the requirement of: (c) a surface on a tire cavity side of a film (2, 2A) positioned on a tire cavity side in the overlap splice portion being formed with a recess so that a film (2, 2A) thickness (t) at the overlap splice portion becomes thinner than a film (2, 2a) thickness of portions other than the overlap splice portion. an overlap splice portion in which an inner liner configured from a film whose main component is a thermoplastic resin is adhered to an inner side of a carcass layer of a tire via a tie rubber sheet and end portions in a tire circumferential direction (X-X) of the film overlap via a tie rubber across a tire width direction (E-E), the pneumatic tire satisfying the requirements of: (a) a surface (2A0) on a tire outer circumferential side of the film (2, 2A) positioned on the tire cavity side in the overlap splice portion being formed flat between the overlap splice portion and the portions other than the overlap splice portion; and (b) a surface on a tire cavity side and a surface on a tire outer circumferential side (2B0) of a film (2, 2B) positioned on a tire outer circumferential side in the overlap splice portion being formed flat between the overlap splice portion and the portions other than the overlap splice portion characterized in that the tire further satisfies the requirement of: (c) a surface on a tire cavity side of a film (2, 2A) positioned on a tire cavity side in the overlap splice portion being formed with a recess so that a film (2, 2A) thickness (t) at the overlap splice portion becomes thinner than a film (2, 2a) thickness of portions other than the overlap splice portion. (a) a surface (2A0) on a tire outer circumferential side of the film (2, 2A) positioned on the tire cavity side in the overlap splice portion being formed flat between the overlap splice portion and the portions other than the overlap splice portion; and (b) a surface on a tire cavity side and a surface on a tire outer circumferential side (2B0) of a film (2, 2B) positioned on a tire outer circumferential side in the overlap splice portion being formed flat between the overlap splice portion and the portions other than the overlap splice portion characterized in that the tire further satisfies the requirement of: (c) a surface on a tire cavity side of a film (2, 2A) positioned on a tire cavity side in the overlap splice portion being formed with a recess so that a film (2, 2A) thickness (t) at the overlap splice portion becomes thinner than a film (2, 2a) thickness of portions other than the overlap splice portion.
