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.
