摘要： A pneumatic tire can include a tread portion, a pair of sidewall portions, bead portions, and a carcass. At least one sidewall portion can include a first sidewall rubber arranged outside the carcass in a tire axial direction. The first sidewall rubber can include a different color rubber layer and a barrier rubber layer. The different color rubber layer can have a color different from a basic color of an outer surface of the at least one sidewall portion. At least a part of the different color rubber layer can be exposed in the outer surface of the at least one sidewall portion. The barrier rubber layer can be arranged between the different color rubber layer and the carcass. The barrier rubber layer can include a first portion having a rubber compounding to suppress migration of rubber compounding agents on the carcass side to the different color rubber layer.

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.
