A pneumatic tyre includes a carcass extending between bead cores disposed in respective bead portions through a tread portion and sidewall portions, and bead apex rubbers each extending radially outwardly from the respective bead cores, each bead apex rubber having an inner side surface in a tyre axial direction. In a tyre cross-section under a standard inflated state, a ratio h1/H of a carcass-maximum-width height h1 to a carcass-maximum height H is equal to or less than 50%, and in at least one bead portion, an angle of a tangent line touching the inner surface of the bead apex rubber at an intersection of a tyre radial reference line passing a rim-width location of the standard wheel with the inner side surface of the bead apex rubber is in a range of from 55 to 75 degrees to the tyre radial reference line.
