A pneumatic tire having a tie layer for adhering a DVA film used as a barrier layer to a tire layer, for example, a ply layer, and a method for producing the same. A pneumatic tire including a tread and a barrier layer disposed inside the tread. The barrier layer includes a dynamic vulcanization alloy. A tire layer, such as the ply layer 18, is disposed between the barrier layer and the tread and includes a rubber compound having a diene rubber. The tie layer 22 is disposed between the barrier layer and the tire layer. The tie layer comprises a rubber compound having 100 parts of a rubber mixture selected from 10 to 50 parts nitrile rubber, 20 to 70 parts natural rubber, and 10 to 30 parts synthetic polyisoprene rubber, In addition, it comprises at least one reinforcing filler, at least one tackifier, and optionally at least one process oil. The tie layer is directly bonded to the barrier layer and the tire layer, which can be the innermost layer. [Selection] Figure 1 |
