The present invention can provide a rubber composition, in which all of strength at break, low heat-build up property, run-flat durability and low fuel consumption can be improved since the rubber composition comprises 5 to 120 parts by weight of flake-like graphite having an average aspect ratio of 3 to 80 and an average particle diameter of 2 to 80 µm on the basis of 100 parts by weight of a diene rubber component, and a run-flat tire using the rubber composition. |
