RUBBER COMPOSITION AND PNEUMATIC TIRE HAVING TREAD FABRICATED USING RUBBER COMPOSITION

摘要

Provided are: a rubber composition in which fuel economy, abrasion resistance, and wet grip performance are improved with a good balance thereof while obtaining good workability; and a pneumatic tire having a tread fabricated using the rubber composition. The present invention relates to a rubber composition containing a copolymer synthesized by copolymerization of conjugated-diene-based monomers and a compound represented by formula (1), and carbon black and/or silica. (In formula (1), R11 and R12 are the same or different and represent hydrogen atoms or C1-30 hydrocarbon groups.)
