A pneumatic tire comprising: a carcass comprising a carcass ply comprising a main body portion extending between a pair of bead cores of bead portions via a tread portion and sidewall portions and a pair of turned up portions each turned up around respective one of the bead cores from an inside to an outside in a tire axial direction; a pair of bead apex rubbers each extending outwardly in a tire radial direction between the main body portion and respective one of the turned up portions, each of the bead apex rubbers comprising a first rubber portion and a second rubber portion provided on an outer side in the tire axial direction of the first rubber portion and having smaller rubber hardness than the first rubber portion, and in a standard state in which the pneumatic tire is mounted on a standard rim, inflated to an standard pressure, and loaded with no tire load, a ratio H1/H2 of a height H1 of an outer end in the tire radial direction of the first rubber portion from a bead base line and a height H2 of an outer end in the tire radial direction of each of the turned up portions from the bead base line being in a range of from 1.4 to 1.7, wherein the pneumatic tire further comprises a pair of bead reinforcing layers each extending around respective one of the bead cores along the carcass ply in a substantially U-shaped manner in a cross section thereof, wherein each of the bead reinforcing layers comprises an inner portion extending on an inner side in the tire axial direction of the main body portion and an outer portion extending on the outer side in the tire axial direction of corresponding one of the turned up portions, and a ratio Ta/T1 of thickness (Ta) in the tire axial direction of the first rubber portion and thickness in the tire axial direction of the bead apex rubber at a position of the outer end in the tire radial direction of the turned up portion is smaller than a ratio Tb/T2 of thickness (Tb) in the tire axial direction of the first rubber portion and thickness in the tire axial direction of the bead apex rubber at a position of an outer end in the tire radial direction of the outer portion, characterized in that a ratio (Ta/T1)/(Tb/T2) of the ratio Ta/T1 and the ratio Tb/T2 is in a range of from 0.60 to 0.70. a carcass comprising a carcass ply comprising a main body portion extending between a pair of bead cores of bead portions via a tread portion and sidewall portions and a pair of turned up portions each turned up around respective one of the bead cores from an inside to an outside in a tire axial direction; a pair of bead apex rubbers each extending outwardly in a tire radial direction between the main body portion and respective one of the turned up portions, each of the bead apex rubbers comprising a first rubber portion and a second rubber portion provided on an outer side in the tire axial direction of the first rubber portion and having smaller rubber hardness than the first rubber portion, and in a standard state in which the pneumatic tire is mounted on a standard rim, inflated to an standard pressure, and loaded with no tire load, a ratio H1/H2 of a height H1 of an outer end in the tire radial direction of the first rubber portion from a bead base line and a height H2 of an outer end in the tire radial direction of each of the turned up portions from the bead base line being in a range of from 1.4 to 1.7, wherein the pneumatic tire further comprises a pair of bead reinforcing layers each extending around respective one of the bead cores along the carcass ply in a substantially U-shaped manner in a cross section thereof, wherein each of the bead reinforcing layers comprises an inner portion extending on an inner side in the tire axial direction of the main body portion and an outer portion extending on the outer side in the tire axial direction of corresponding one of the turned up portions, and a ratio Ta/T1 of thickness (Ta) in the tire axial direction of the first rubber portion and thickness in the tire axial direction of the bead apex rubber at a position of the outer end in the tire radial direction of the turned up portion is smaller than a ratio Tb/T2 of thickness (Tb) in the tire axial direction of the first rubber portion and thickness in the tire axial direction of the bead apex rubber at a position of an outer end in the tire radial direction of the outer portion, characterized in that a ratio (Ta/T1)/(Tb/T2) of the ratio Ta/T1 and the ratio Tb/T2 is in a range of from 0.60 to 0.70.
