There is provided a rubber composition whose run-flat durability is improved and in which precipitation of sulfur and a vulcanization accelerator on the rubber surface before vulcanization is prevented. Sulfur in an amount of 2 to 8 parts by weight and two or more vulcanization accelerators in an amount of at least 5 parts by weight based on 100 parts by weight of a rubber component are used, at least one of the accelerators being a sulfen amide accelerator.
