<p>Disclosed is a run-flat tire having greatly increased run-flat endurance. The disclosed run-flat tire is provided with: a carcass (6) going from a tread section (2) through a sidewall section (3) to a bead core (5) of a bead section (4); and a side-reinforcement rubber layer (9) that has a crescent-shaped cross-section and is disposed inside the carcass (6) in the sidewall section (3). A heat-conducting rubber (11) having a coefficient of thermal conductivity of at least 0.3 W/(m·K) is distributed on the inner surface (12) of the tire. At least part of said heat-conducting rubber (11) is distributed in a side-reinforcement rubber layer projection area (T), consisting of the projection of the side-reinforcement rubber layer (9) onto the inner surface (12) of the tire.</p> |
