Beschreibung
Zusammenfassung:	Described herein are tires comprising a rubber composition based on at least an elastomer matrix comprising from 50 to 100 phr of one or more copolymers of butadiene and of vinylaromatic monomer, having a content of vinylaromatic units of between 0 and 5% by weight and a Tg within a range extending from −110° C. to −70° C.; and a hydrocarbon resin, wherein the hydrocarbon resin is based on a cyclic monomer selected from the group consisting of a distillation cut from a petroleum refinery stream, and/or C4, C5 or C6 cyclic olefins and mixtures thereof, and wherein 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) H Ar≤6 mol %, (2) Tg≥95−2.2(H Ar), (3) Tg≥125−(0.08Mn).
