Zusammenfassung:Provided is a pneumatic tire which makes it possible to suppress variation in thickness of a sealant layer by reducing overlapping regions of a sealant material, and achieve improvement in the adhesiveness of a sound absorption layer with respect to the sealant layer. The present invention is provided with: a sealant layer 60 disposed to the tire internal cavity side of an inner liner 50; and a sound absorption layer 70 disposed to the tire internal cavity side of the sealant layer 60. The sealant layer 60 is formed from a belt-shaped sealant material 61 that is stuck to an inner surface 501 of the inner liner 50 while being rotated. The sealant layer 60 has: a plurality of annular circulation parts 62 that are in parallel to the tire circumferential direction and that are disposed in parallel to each other in a state where the sealant material 61 is disposed adjacent to the same in the tire width direction; and a plurality of shift parts 63 which are each provided to a portion of a circulation part 62 in the tire circumferential direction and at each of which the sealant material 61 is shifted to a circulation part 62 located adjacent on one side in the tire width direction.
