This run flat tire includes a carcass toroidally extending between two bead portions and side reinforcing rubber, having a crescent cross-sectional shape in the tire width direction, on the tire width direction inside of the carcass. The relational expressions 0.09 ‰¤ TWH/TW ‰¤ 0.19, D/SH ‰¤ 0.05, and 0.89 ‰¤ TW/SW ‰¤ 0.94 are satisfied, where, in a reference state such that the run flat tire is mounted on an applicable rim and inflated to a prescribed internal pressure with no load, TW (mm) represents the half width in the tire width direction between the tread edges, TWH (mm) represents the radial drop height of the tread edge, SW (mm) represents half of the tire maximum width, SH (mm) represents the tire cross-sectional height, and D (mm) represents the drop height of the tire at a position 0.6SW (mm) outward, in the tire width direction, from the tire equatorial plane. |
