  • Patent number: 11802195
    Abstract: In a first aspect, the present invention is directed to a rubber composition comprising, based on 100 parts by weight of elastomer (phr), 70 phr to 95 phr of diene based elastomer, wherein said diene based elastomer comprises 25 phr to 60 phr of a first diene based elastomer having a glass transition temperature within a range of ?49° C. to ?15° C., and 10 phr to 45 phr of a second diene based elastomer having a glass transition temperature within a range of ?50° C. to ?110° C., 5 phr to 30 phr of one or more of natural rubber and synthetic polyisoprene rubber, 40 phr to 70 phr of silica, and 10 phr to 40 phr of at least one terpene resin having a weight average molecular weight (Mw) of at least 900 g/mol. In another aspect, the present invention is directed to tire comprising a tire tread with aforementioned rubber composition.
