1. A run-flat radial tire comprising:
a carcass spanning between a pair of bead portions; a vehicle mounting direction outer side side-reinforcing rubber layer that is provided at a tire side portion at a vehicle mounting direction outer side and that extends in a tire radial direction along an inner face of the carcass; and a vehicle mounting direction inner side side-reinforcing rubber layer that is provided at a tire side portion at a vehicle mounting direction inner side and that extends in the tire radial direction along an inner face of the carcass, a tire radial direction outer side end portion of the vehicle mounting direction inner side side-reinforcing rubber layer being closer to a tire equatorial plane than a tire radial direction outer side end portion of the vehicle mounting direction outer side side-reinforcing rubber layer, wherein a tire cross-section height of the run-flat radial tire is 115 mm or more than 115 mm. |
