摘要： [Object] A pneumatic tire 2 which is excellent in durability is provided.
[Solution] The tire 2 includes adhesive sheet layers 28. Each adhesive sheet layer 28 includes an interposed portion 58 and a protruding portion 60. The interposed portion 58 is interposed between a base layer 32 and a cap layer 34 of a tread 4. The protruding portion 60 is layered over a carcass 12. The adhesive sheet layers 28 are obtained by a rubber composition being crosslinked. The rubber composition contains a tackifier. A width W1 of the interposed portion 58 is preferably greater than or equal to 5 mm, and preferably not greater than 20 mm. A width W2 of the protruding portion 60 is preferably greater than or equal to 10 mm, and preferably not greater than 20 mm. A thickness of each adhesive sheet layer 28 is preferably greater than or equal to 0.5 mm, and preferably not greater than 2.0 mm. A ratio of an adhesive strength of each adhesive sheet layer 28 to an adhesive strength of the cap layer 34 is preferably greater than or equal to 1.30.
