A pneumatic tyre comprising: a tread portion; two axially spaced sidewall portions extending inwardly in a tyre radial direction from the tread portion, at least one of the sidewall portions being provided with a side protector that protrudes outwardly in a tyre axial direction, the side protector having an inner end in the tyre radial direction located outwardly in the tyre radial direction of a tyre-maximum-width position; two axially spaced bead portions connected to inward in the tyre radial direction of the respective sidewall portions, each bead portion comprising a bead apex rubber, the bead apex rubber having an outer end in the tyre radial direction being located inwardly in the tyre radial direction of the tyre-maximum-width position; and at least one carcass ply (6A, 6B) extending between the bead portions; wherein the bead portions comprise bead cores, and wherein in each bead portion, the bead apex rubber comprises a main apex that extends outwardly in the tyre radial direction from an outer surface in the tyre radial direction of the bead core, and an outer apex disposed outwardly in the tyre axial direction of the main apex, characterized in that a length in the tyre radial direction of a tyre inner region from a bead baseline to the outer end of each bead apex rubber is in a range of from 0.8 to 1.2 times a length in the tyre radial direction of a tyre outer region from an outermost position of the tread portion in the tyre radial direction to the inner end of the side protector, and the at least one carcass ply (6A, 6B), in each bead portion, extends between the main apex and the outer apex. a tread portion; two axially spaced sidewall portions extending inwardly in a tyre radial direction from the tread portion, at least one of the sidewall portions being provided with a side protector that protrudes outwardly in a tyre axial direction, the side protector having an inner end in the tyre radial direction located outwardly in the tyre radial direction of a tyre-maximum-width position; two axially spaced bead portions connected to inward in the tyre radial direction of the respective sidewall portions, each bead portion comprising a bead apex rubber, the bead apex rubber having an outer end in the tyre radial direction being located inwardly in the tyre radial direction of the tyre-maximum-width position; and at least one carcass ply (6A, 6B) extending between the bead portions; wherein the bead portions comprise bead cores, and wherein in each bead portion, the bead apex rubber comprises a main apex that extends outwardly in the tyre radial direction from an outer surface in the tyre radial direction of the bead core, and an outer apex disposed outwardly in the tyre axial direction of the main apex, characterized in that a length in the tyre radial direction of a tyre inner region from a bead baseline to the outer end of each bead apex rubber is in a range of from 0.8 to 1.2 times a length in the tyre radial direction of a tyre outer region from an outermost position of the tread portion in the tyre radial direction to the inner end of the side protector, and the at least one carcass ply (6A, 6B), in each bead portion, extends between the main apex and the outer apex.
