The present invention is a pneumatic tire (1) including an inner liner (9) and a carcass ply (6) provided adjacent to the inner liner (9) and having a cord (K) embedded in a rubber layer. The inner liner (9) is composed of a polymer layer stack including a first layer of a polymer composition containing SIBS and at least one kind of rubber component selected from among natural rubber, isoprene rubber and butyl rubber, the first layer having a thickness of 0.05 mm to 0.6 mm, and a second layer of a polymer composition containing at least either one of SIS and SIB as well as at least one kind of rubber component selected from among natural rubber, isoprene rubber and butyl rubber, the second layer having a thickness of 0.01 mm to 0.3 mm. The second layer is arranged so as to be in contact with the rubber layer of the carcass ply (6). A distance L from a plane passing through the center of cross section of the cord to the second layer is more than or equal to 0 and less than or equal to (1+D/2) mm where D denotes the diameter of the cord. |
