To provide a tire that achieves both abrasion resistance and low rolling resistance at a high level and to provide carbon black that is suitable for producing a rubber composition for the tire.SOLUTION: Carbon black suitable for use in a rubber composition for a tire is characterized by having a dibutyl phthalate absorption amount of 150 to 170 mL/100 g, a compressed dibutyl phthalate absorption amount of 110 to 120 mL/100 g, a difference between the dibutyl phthalate absorption amount and the compressed dibutyl phthalate absorption amount of 35 to 60 mL/100 g, a cetyltrimethylammonium bromide specific surface area of 90 to 140 m2/g, a hydrogen generation amount of 3,000 to 4,000 ppm and a ratio (ΔD50/Dst) between a mode diameter Dst and a half-value width ΔD50 of the peak including the Dst in the aggregate distribution obtained by a centrifugal sedimentation method of 0.65 to 0.75.SELECTED DRAWING: None
