Beschreibung
Zusammenfassung:	This invention relates to a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads; wherein said tread is adapted to be ground-contacting; wherein the tread is comprised of: (1) an amino group containing rubbery polymer, wherein said amino group containing rubbery polymer contains from about 0.1 weight percent to about 20 weight percent monomer units containing an amino group, (2) from 0.1 to about 25 phr of an organophilic 2:1 layered silicate clay selected from the group consisting of montmorillonite clays, bentonite clays, hectorite clays, saponite clays, nontronite clays, beidellite clays, fluorohectorite clays, stevensite clays, volkonskoite clays, sauconite clays, and laponite clays, and (3) a silica coupling agent.
