A run flat tire comprising: a carcass extending, through a tread portion and a pair of sidewall portions , between bead cores respectively embedded in a pair of bead portions ; side-reinforcing rubber layers each having a crescent-shaped cross section and respectively disposed in the pair of sidewall portions ; and bead apex rubbers disposed outward of a pair of the bead cores in a tire radial direction and extending in the tire radial direction so as to be tapered, wherein each bead apex rubber includes a first bead apex rubber extending from the corresponding bead core outward in the tire radial direction, and a second bead apex rubber disposed outward of the first bead apex rubber in a tire axial direction, characterised in that the carcass includes a first carcass ply composed of a layer of a first carcass cord, and a second carcass ply composed of a layer of a second carcass cord, each of the first carcass ply and the second carcass ply includes a body portion extending between the bead cores so as to form a toroidal shape, and turned-up portions connected to the body portion and each turned up around the corresponding bead core from an inner side to an outer side in the tire axial direction, each turned-up portion of the first carcass ply extends in the tire radial direction through an outer side, in the tire axial direction, of the second bead apex rubber , and each turned-up portion of the second carcass ply extends in the tire radial direction so as to pass between the first bead apex rubber and the second bead apex rubber . a carcass extending, through a tread portion and a pair of sidewall portions , between bead cores respectively embedded in a pair of bead portions ; side-reinforcing rubber layers each having a crescent-shaped cross section and respectively disposed in the pair of sidewall portions ; and bead apex rubbers disposed outward of a pair of the bead cores in a tire radial direction and extending in the tire radial direction so as to be tapered, wherein each bead apex rubber includes a first bead apex rubber extending from the corresponding bead core outward in the tire radial direction, and a second bead apex rubber disposed outward of the first bead apex rubber in a tire axial direction, characterised in that the carcass includes a first carcass ply composed of a layer of a first carcass cord, and a second carcass ply composed of a layer of a second carcass cord, each of the first carcass ply and the second carcass ply includes a body portion extending between the bead cores so as to form a toroidal shape, and turned-up portions connected to the body portion and each turned up around the corresponding bead core from an inner side to an outer side in the tire axial direction, a first bead apex rubber extending from the corresponding bead core outward in the tire radial direction, and a second bead apex rubber disposed outward of the first bead apex rubber in a tire axial direction, characterised in that the carcass includes a first carcass ply composed of a layer of a first carcass cord, and a second carcass ply composed of a layer of a second carcass cord, each of the first carcass ply and the second carcass ply includes a body portion extending between the bead cores so as to form a toroidal shape, and turned-up portions connected to the body portion and each turned up around the corresponding bead core from an inner side to an outer side in the tire axial direction, each turned-up portion of the first carcass ply extends in the tire radial direction through an outer side, in the tire axial direction, of the second bead apex rubber , and each turned-up portion of the second carcass ply extends in the tire radial direction so as to pass between the first bead apex rubber and the second bead apex rubber . <EOS>
