PROBLEM TO BE SOLVED: To provide a pneumatic tire for run flat enhancing run flat durability in addition to enhancement of operation stability by light weight of the tire. SOLUTION: In the pneumatic tire for run flat, a carcass layer 3 is laid between a pair of left and right bead parts 2 and a reinforcement rubber 9 comprising a hard rubber of crescent cross section is arranged on a side wall part 8. A thermal conductive member 10 having thermal conductivity of 0.3 kcal/mh°C or higher is extended in a tire radial direction while contacted with a reinforcement rubber 9 and is arranged such that a periphery of a bead core 5 of a bead part 2 is folded/returned and the inside of the tire is extended to an outer side in a tire radial direction along a surface of the side wall part 8.
