A pneumatic tyre includes a pair of bead portion 4, a pair of bead cores 5, a carcass 6 extending between the pair of bead cores 5, and a pair of bead apex rubbers. Each bead core 5 includes a core inner surface on an inner side in the tyre radial direction of the bead core 5. In a pre-assemble state, each core inner surface has an angle of 20 degrees plus/minus 2 degrees to the tyre axial direction, and is inclined outwardly in the tyre radial direction toward an outer side in the tyre axial direction. The bead apex rubber includes a first rubber portion 10 arranged so as to cover a circumference of the bead core 5 and having a circular or substantially elliptical outline, and a second rubber portion 11 tapering outwardly in the tyre radial direction from the first rubber portion 10. The first rubber portion 10 is greater in hardness than the second rubber portion 11.
