    • Provided is a pneumatic radial tire in which run-flat durability can be improved while inhibiting vibration during tire rolling and tire protrusion during high-speed traveling. A pneumatic radial tire comprising a side reinforcing rubber layer 5 having a crescent shaped cross-section arranged on the inside of a carcass 4 at a side wall portion 2, and a belt reinforcing layer 9 which is formed by spirally winding a strip which is formed by covering a polyester cord with rubber with respect to the tire circumferential direction. The polyester cord taken out from pneumatic radial tire satisfies that the ply twist coefficient α1 and the cable twist coefficient α2 represented by the following formulae: α ⁢ 1 = N ⁢ 1 × 0.125 × D ⁢ 1 / ρ 0.5 × 10 - 3 α ⁢ 2 = N ⁢ 2 × 0.125 × D ⁢ 2 / ρ 0.5 × 10 - 3
      are 0.1 to 0.4 and 0.1 to 0.45, respectively, and the initial tensile resistance degree is 7 to 20 GPa, and the adhesion level of the polyester cord in a residual adhesion evaluation method after an adhesive agent treatment is 5 N/cord or higher.
