The tread rubber includes a first rubber layer comprising a first rubber and forming the tread surface, and a second rubber layer comprising a second rubber and being adjacent inwardly in a tire radial direction of the first rubber layer. A loss tangent tan δa of the first rubber at 100 degrees C. is smaller than a loss tangent tan δb of the second rubber at 100 degrees C. A glass transition temperature of the first rubber is lower than a glass transition temperature of the second rubber.",
