Abstract
The present invention is directed a tire comprising two rubber components which are co-cured together. The first rubber component comprises from 70 phr to 100 phr of a hydrogenated styrene butadiene rubber, 0 phr to 15 phr of a polybutadiene, 5 phr to 20 phr of a polyoctenamer, and 40 phr to 160 phr of a first filler. The second rubber component comprises 90 phr to 100 phr of a diene-based elastomer; and 20 phr to 160 phr of a second filler. Moreover, the present invention is directed to a rubber composition comprising a hydrogenated styrene butadiene rubber, 5 phr to 20 phr of a polyoctenamer, and 40 phr to 160 phr of a reinforcing filler.
