The present invention is directed to a rubber composition comprising 30 to 80 phr of a first styrene butadiene rubber having a glass transition temperature lower than −50° C.; 10 to 40 phr of a second styrene butadiene rubber having a glass transition temperature higher than −45° C.; and 10 to 30 phr of a further rubber selected from the list of synthetic polyisoprene, natural rubber and polybutadiene. Furthermore, the rubber composition comprises 80 phr to 140 phr of silica and 40 phr to 90 phr of a hydrocarbon resin having a glass transition temperature of at least 30° C. and being selected from the group of C5 resins and C5/C9 resins. The present invention is also directed to a tire comprising such a rubber composition.
