A pneumatic tyre includes a pair of bead portions, a pair of bead cores, and a carcass extending between the bead cores. The carcass includes a carcass ply including a main portion extending between the bead cores and a pair of turn-up portions each turned up around a respective one of the bead cores from axially inside to the outside of the tyre and extending radially outwardly. In at least one of the bead portions, a reinforcing rubber layer is disposed outwardly and adjacently in the tyre axial direction of the turn-up portion. The reinforcing rubber layer includes a first rubber layer and a second rubber layer arranged outwardly in the tyre axial direction of the first rubber layer. A loss tangent tanδ1 of the first rubber layer is smaller than a loss tangent tanδ2 of the second rubber layer.
