Tire with rubber tread containing combination of resin blend and functionalized elastomer

This invention relates to a pneumatic tire with an outer, running surface containing, circumferential tread comprised of a styrene/butadiene (SBR) rich rubber composition containing two SBR's with spaced apart glass transition temperatures (Tg's), one of which is a functionalized SBR with a functional group together with a combination of at least three resins with spaced apart softening points. The filler reinforcement is a combination of silica and rubber reinforcing carbon black.
