  "textContent": "The invention relates to a tire having a tread of a rubber composition with compositional limitations containing minimal, if any, of in situ formed volatile alcohol byproduct. The tread component rubber composition contains a combination of pre-hydrophobated silica reinforcement and siloxane functionalized styrene/butadiene copolymer elastomer. The pre-hydrophobated silica is prepared, prior to mixing with the elastomer(s), by reacting hydroxyl groups (e.g. silanol groups) contained on the surface of a precipitated silica with an alkoxyorganomercaptosilane or with a bis-3(triethoxysilylpropyl) polysulfide which contains an average of from 2 to 4 connecting sulfur atoms in its polysulfidic bridge to form a composite thereof which may optionally include an alkyl silane. The volatile alcohol byproduct (e. g. ethanol) therefrom is thereby removed from the pre-hydrophobated silica composite prior to its introduction into the rubber composition(s).",
