    摘要： This invention discloses a pneumatic 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 (a) about 60 phr to about 90 phr of a cis-1,4-polybutadiene rubber, wherein the cis-1,4-polybutadiene rubber has a glass transition temperature which is within the range of about −104° C. to about −80° C., (b) about 10 phr to about 40 phr of at least one additional rubbery polymer selected from the group consisting of polyisoprene rubber, polybutadiene rubber, isoprene-butadiene rubber, and styrene-isoprene-butadiene rubber, wherein the additional rubbery polymer has a glass transition temperature which is within the range of about −30° C. to about −10° C., and (c) about 20 phr to about 60 phr of carbon black, wherein the carbon black has a dibutylphthalate absorption value of at least 140 cm3/100 grams and wherein the carbon black has a cetyl trimethyl ammonium bromide adsorption area which is within the range of about 60 to about 90.

    摘要： The invention relates to a tire having at least one component (e.g. tread) of a rubber composition comprised of a composite of styrene/butadiene elastomer and functionalized styrene/butadiene elastomer containing an internal silanol and/or siloxy group therein with pendent silanol and/or alkoxy groups of a polymodal (e.g. bimodal) molecular weight distribution and a dispersion therein of silica aggregates of which a portion thereof contain a plurality of hydroxyl groups on their surface in a form of geminal hydroxyl groups. In one aspect, said silica aggregates may be pre-treated to reduce said hydroxyl groups on their surface prior to blending with said silanol and/or siloxy functionalized elastomer.
