Abstract

Rubber compositions and articles made from such rubber compositions that are based upon a cross-linkable elastomer composition, the 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 %. Such rubber compositions may further include between 30 phr and 150 phr of a plasticizing resin, silica and a coupling agent that is a monohydroxysilane polysulfide having a form (Formula I) wherein radicals R, identical or different, are hydrocarbon groups, radicals R', identical or different, are divalent linking groups and x is equal to or greater than 2.
