Rubber compositions, rubber articles and methods for making such rubber articles that include a rubber composition having, per 100 parts by weight of rubber (phr), a modified rubber component such as an epoxidized rubber component selected from an epoxidized polybutadiene rubber (eBR), an epoxidized styrene-butadiene rubber (eSBR), or combinations thereof having a Tg of between −80° C. and −110° C. as well as a second rubber component selected from the group consisting of a polybutadiene rubber (BR), a styrene-butadiene rubber (SBR) and combinations thereof. Also between 30 phr and 130 phr of an efficient plasticizing resin may be included. An efficient plasticizing resin is one that when included in a mixture of the modified rubber component and 67 phr of the efficient plasticizing resin, causes a Tg of the mixture to be at least 14° C. higher than the Tg of the modified rubber component itself.
