Abstract
The purpose of the present invention is to provide a rubber composition in which a rubber viscosity during kneading is low and processability is good though the rubber composition comprises a white filler, and fuel efficiency and abrasion resistance are good. A rubber composition comprising a rubber component, a white filler and a compound represented by the following formula (1), where Rrepresents an alkyl group or alkenyl group having 8 to 14 carbon atoms, the alkyl group or alkenyl group may be linear, branched or cyclic, and Rrepresents a hydroxyalkyl group or a hydroxyalkyl group having an oxyalkylene unit.
