To provide a pneumatic tire capable of improving the durability of connection points between partition wall parts and a tire inside surface.In a pneumatic tire 10, partition wall parts 24 that extend inward in a tire radial direction from a tire inside surface 17 of tire shoulder parts 21 and whose tire radial direction inside ends contact a rim 12 are disposed. A pair of right and left reinforcement layers 38 are disposed in regions ranging from the partition wall parts 24 to tire side parts 20 via connection parts 29 between the partition wall parts 24 and the tire inside surface 17 such that the reinforcement layers 38 continue from the partition wall parts 24 to the tire side parts 20 via the connection parts 29 between the partition wall parts 24 and the tire inside surface 17. Because of the reinforcement layers 38, the portion of each of the connection parts 29 between the partition wall parts 24 and the tire inside surface 17 where a first carcass ply 32 is disposed and the portion thereof where a second carcass ply 37 is disposed can be prevented from separating, whereby the durability of the connection parts 29 of the partition wall parts 24 can be improved in comparison to what has conventionally been the case.
