A tire tread manufactured at least in part from a rubber composition that is based upon a cross-linkable elastomer composition comprising between 80 phr and 100 phr of a polybutadiene-based elastomer modified with a functional group that is capable of interacting with a silica reinforcing filler, wherein a polybutadiene portion of the polybutadiene-based elastomer has between 8 wt % and 15 wt % vinyl units, wherein the polybutadiene-based elastomer includes at least 30 mol % trans-bonds, and wherein the polybutadiene-based elastomer has a glass transition temperature of between −100° C. and −80° C. Such rubber composition is cured with a peroxide curing agent and includes an organosilane coupling agent having in some embodiments no or little sulfur content.
