Beschreibung
Zusammenfassung:	A rubber composition that is capable of providing vulcanized rubber excellent in the abrasion resistance without the deterioration of the crack resistance and the low heat generation property is provided. The rubber composition contains: (A) a rubber component; (B) carbon black having a CTAB specific surface area of 110 to 160 m2/g, a half value width ΔD50of a peak including a Stokes equivalent diameter Dstobtained by a centrifugal sedimentation method of 60 nm or less, and ΔD50/Dstof 0.95 or less; and (C) silica having a CTAB specific surface area of 200 m2/g or more, has a total amount of a content (b) of the carbon black (B) and a content (c) of the silica (C) of 30 to 80 parts by mass per 100 parts by mass of the rubber component (A), and has (b)/(c) of (60 to 85)/(40 to 15).
