  • Publication number: 20240424833
    Abstract: Described herein are tires comprising a rubber composition based on at least an elastomer matrix comprising at least one copolymer of butadiene and of vinylaromatic monomer and a hydrocarbon resin. The hydrocarbon resin is based on a cyclic monomer selected from the group consisting of a distillation cut from a petroleum refinery stream, C4, C5 and C6 cyclic olefins and mixtures thereof. The hydrocarbon resin has a content of aromatic protons (H Ar, expressed in mol %), a glass transition temperature (Tg, expressed in ° C.), and a number average molecular weight (Mn, expressed in g/mol) that are represented by (1) 12 mol %?H Ar?19 mol %, (2) Tg?95?2.2*(H Ar), (3) Tg??53+(0.265*Mn) and (4) 300 g/mol?Mn?450 g/mol.
