Abstract:
The invention provides a pneumatic tire which can reduce a rolling resistance while maintaining an wear resistance. Among a cap portion in a center area, at least the cap portion of a center land portion is provided with a cap front layer which includes a surface, and a cap inner layer which is laminated in an inner periphery of the cap front layer. A loss tangent of the cap front layer is set to be smaller than a loss tangent of the cap inner layer and be smaller than a loss tangent of the cap portions in the shoulder areas.
