An elastomeric composition is disclosed. The elastomeric composition includes, per (100) parts by weight of rubber (phr): about 0 to about 25 phr of polybutadiene having a cis-l,4 linkage content of at least 95%; about 75 to 100 phr of a styrene/butadiene copolymer; about 10 to about 30 phr of a processing oil; about 50 to about 70 phr of a filler; a curative agent; an antioxidant; a silane coupling agent; and about 5 to about 30 phr of a propylene-ethylene-diene terpolymer.

    L'invention concerne une composition élastomère. La composition élastomère comprend, pour 100 parties en poids de caoutchouc (phr) : environ 0 à environ 25 phr de polybutadiène présentant une teneur en liaisons cis-l,4 d'au moins 95 % ; environ 75 à 100 phr d'un copolymère styrène/butadiène ; environ 10 à environ 30 phr d'une huile de traitement ; environ 50 à environ 70 phr d'une charge ; un agent durcisseur ; un antioxydant ; un agent de couplage au silane ; et environ 5 à environ 30 phr d'un terpolymère propylène-éthylène-diène.
