A rubber composition that is based upon a cross-linkable elastomer composition comprising, per 100 parts by weight of rubber (phr) between 70 phr and 100 phr of an epoxidized rubber component selected from an epoxidized polybutadiene rubber (eBR), an epoxidized styrene-butadiene rubber (eSBR), or combinations thereof, wherein the epoxidized rubber component has a Tg of between −80° C. and −110° C. and an epoxy-function content of between 1 mol % and 25 mol %; between 30 phr and 150 phr of a plasticizing resin; and a quickly reactive silica that provides a macro dispersion Z-value of at least 50 in a defined rubber composition; and a non-silol coupling agent.
