RUBBER COMPOSITION, RUBBER COMPOSITION FOR TIRE TREAD, CROSSLINKED RUBBER AND TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition useful for producing rubber having improved tackiness without impairing abrasion resistance and crack growth resistance, a crosslinked rubber obtained by crosslinking the rubber composition and tires using the rubber composition or the crosslinked rubber.SOLUTION: A rubber composition comprises a conjugated diene-nonconjugated olefin copolymer and a tackifier. A crosslinked rubber is obtained by crosslinking the rubber composition. A tire uses the rubber composition or the crosslinked rubber.
