RUBBER COMPOSITION AND A TIRE

In a first aspect, the present invention is directed to a rubber composition comprising 70 phr to 95 phr of styrene butadiene rubber comprising at least 5 phr of a first styrene butadiene rubber having a glass transition temperature within a range of −49° C. to −15° C. and at least 45 phr of a second styrene butadiene rubber having a glass transition temperature within a range of −50° C. to −89° C., wherein the rubber composition comprises more of the second styrene butadiene rubber than of the first styrene butadiene rubber. Moreover, the rubber composition comprises 5 phr to 30 phr of one or more of natural rubber and synthetic polyisoprene; 135 phr to 200 phr of silica; and at least 55 phr of at least one hydrocarbon resin comprising at least one terpene resin having a glass transition temperature of at least 30° C.
