Beschreibung
Zusammenfassung:	The present invention provides: a rubber composition obtained by mixing 30 to 80 parts by mass of carbon black, whose DBP absorption value and CTAB adsorption specific surface area satisfy the following relational formulas (I) and (II), into 100 parts by mass of a rubber component, wherein macrodispersion D(%) of the carbon black in the rubber composition is 1% or more and less than 10%, and the rubber composition has high performance and excellent processability such as roll workability and the like; and a rubber product such as a tire having reduced rolling resistance and excellent fatigue resistance and abrasion resistance. DBP absorption value cm 3 / 100 g < 3.0 × CTAB adsorption specific surface area m 2 / g 270 DBP absorption value cm 3 / 100 g < 115 CTAB adsorption specific surface area m 2 / g < 230
