A pneumatic tyre includes a tread portion having a tread rubber and a tyre inner cavity surface, and a noise damper made of a porous material fixed to the tyre inner cavity surface. The tread rubber includes an outer tread rubber having a ground-contacting surface, and an inner tread rubber disposed inwardly in the tyre radial direction of the outer tread rubber and outwardly in the tyre radial direction of the noise damper. A loss tangent tan δ of the inner tread rubber at 30 degrees C is smaller than a loss tangent tan δ of the outer tread rubber at 30 degrees C.
