Patent abstract
A tire tread formed at least in part from a rubber composition that is based upon a cross-linkable rubber composition that may include between 50 phr and 90 phr of a first highly unsaturated elastomer being middle chain functionalized with an aminoalkoxysilane group and having a Tg of between −108° C. and −45° C. and between 10 phr and 50 phr of a second highly unsaturated elastomer being end-chain functionalized with a silanol group and having a Tg of between −108° C. and −10° C. The rubber composition may further include between 50 phr and 150 phr of a silica filler and a plasticizing system comprising between 5 phr and 120 phr of a plasticizing resin having a Tg of at least 25° C. and between 0 phr and 60 phr of a plasticizing liquid.
