The invention provides rubber compositions comprising: (a) a first elastomer comprising one or more styrene butadiene copolymers having a glass transition temperature, Tg, ranging from −40 to −15° C.; (b) a second elastomer comprising natural rubber; and (c) a hydrocarbon polymer additive component comprising: (i) a first hydrocarbon polymer additive which is a partially hydrogenated C5 resin; and (ii) a second hydrocarbon polymer additive which is a fully hydrogenated resin selected from the group consisting of a hydrogenated C5 resin, a hydrogenated C5/C9 copolymer resin, a hydrogenated C9 resin, and combinations thereof. The rubber compositions are particularly suitable for use in the production of tire components, in particular tire treads.
