    Abstract: This invention relates to a pneumatic rubber tire having a tread of a cap/base layered construction wherein said tire contains a first component as a tread cap layer having a running surface and at least two additional tire rubber components, wherein said tire components are comprised of rubber compositions which contain a maximum of 50 phr of reinforcing filler comprised of a maximum of 30 phr of rubber reinforcing carbon black. In one aspect, a purpose of such maximum of 30 phr of rubber reinforcing carbon black for said plurality of tire components is to promote a relatively low hysteresis property within said tire via such components to thereby promote relatively low rolling resistance for a pneumatic tire which contains such components. In practice, such additional tire components may be, for example, outer sidewall rubber layer, apex, chafer, belt ply and carcass ply components.

    Abstract: The invention relates to a tire having a 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, together with at least 30 phr of cis 1,4-polybutadiene rubber and a dispersion in said rubber composition of precipitated silica aggregates and a coupling agent as a bis (3-triethoxysilylpropyl) polysulfide having an average of from only 2 to 2.5 sulfur atoms in its polysulfidic bridge to the exclusion of a bis (3-trialkoxysilylalkyl) polysulfide having an average of greater than 2.5, and particularly greater than 3, sulfur atoms in its polysulfidic bridge. 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. In one aspect, a carbon black contained in the rubber composition may be an electrically conductive carbon black.

    Abstract: This invention relates to a tire having at least one component (e.g. tread) of a rubber composition comprised of a carbon black and precipitated silica reinforced elastomer blend comprised of a combination of hydroxyl functionalized aqueous emulsion polymerization prepared styrene/butadiene copolymer elastomer (E-SBR) and tin coupled organic solvent solution polymerization prepared styrene/butadiene copolymer elastomer (S-SBR) and/or isoprene/butadiene copolymer elastomer. Preferably, said E-SBR is exclusive of functional groups reactive with alkoxy groups other than said hydroxyl functional groups. A coupling agent as bis(3-triethoxysilylpropyl)polysulfide having an average of from only 2 to 2.6 connecting sulfur atoms in its polysulfidic bridge is used. The invention further relates to an article of manufacture, such as for example a tire, having at least one component of a rubber composition comprised of said elastomer blend.
