摘要:
This invention discloses a tire having enhanced wet traction and ice traction characteristics. These tires are 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 includes at least one circumferential groove which separates circumferential ribs, each circumferential groove having two sides and a base therebetween, and wherein the sides of each circumferential groove are comprised of a rubbery composition that includes silicate microflakes which are substantially aligned in an orientation which is parallel with the sides of the grooves.
