A run-flat tire has a carcass that spans a region between a pair of bead portions, a side reinforcement layer that is provided at a tire side portion that connects the bead portions and a tread portion, an inclined belt layer that is provided at an outer side of the carcass in a tire radial direction so as to span a tire equatorial plane CL, and that is formed by cords that are inclined relative to the tire circumferential direction, and a reinforcement cord layer that is provided at an outer side of the inclined belt layer in the tire radial direction, and only on a half portion of the tire that is located on an inner side in a tire fitting direction of the tire equatorial plane CL, and that is formed by cords that are inclined relative to the tire circumferential direction. |
