Abstract:
A pneumatic tire (1) including bead portions (4) disposed at the inner ends of side wall portions (3) extending inward from both ends of tread portions (2) in a radial direction, and sealing therein a sealant (6) for preventing puncture by a seal rubber sheet (5) extending in a circumferential direction on a tire inner cavity surface inside the tread portion (2), wherein the seal rubber sheet (5) includes a bonding portion (5a) to be integrally bonded at both side edge portions thereof with an inner liner rubber (12) of the tire inner cavity surface and a non-bonding portion (5b) prevented from being bonded to the inner liner rubber (12) due to the interposition of a bonding preventing sheet (13) having a rubber mold-releasing property between the bonding portions (5a and 5b). The sealant (6) is sealed into the bag-like portion defined by the non-bonding portion (5a) between the inner liner rubber (12) and the seal rubber sheet (5).
