The present invention relates to a run-flat tire employing a rubber composition capable of improving processability without reducing the durability during run-flat traveling. More specifically, the present invention relates to a run-flat tire comprising a bead filler 7 and a pair of side-reinforcing rubber layers 8. At least one of the bead filler 7 and the side-reinforcing rubber layer 8 employs a rubber composition obtained by adding 3 to 10 parts by mass of sulfur and 0.1 to 30 parts by mass of a low-molecular-weight conjugated diene-based polymer (B) having a weight average molecular weight in the range of 2,000 to 10,000, to 100 parts by mass of a rubber component (A) containing at least a natural rubber or polyisoprene rubber and having a weight average molecular weight in the range of 150,000 to 2,000,000. |
