    • The present invention is directed to a pneumatic tire comprising a tread, the tread comprising a rubber composition comprising from 20 to 90 parts by weight per 100 parts by weight of rubber (phr) of solution polymerized styrene-butadiene rubber, from 10 to 80 phr of polybutadiene rubber, wherein from 0 to 20 weight percent of the polybutadiene rubber is a syndiotactic polybutadiene rubber comprising at least 70 percent of monomeric units in syndiotactic 1,2 configuration and the balance of the polybutadiene rubber comprises at least 90 percent of monomeric units in cis-1,4 configuration; and from 50 to 150 phr of pre-hydrophobated precipitated silica wherein the pre-hydrophobated precipitated silica is hydrophobated prior to its addition to the rubber composition by treatment with at least one silane selected from the group consisting of alkylsilanes, alkoxysilanes, organoalkoxysilyl polysulfides and organomercaptoalkoxysilanes.
    • 本发明涉及一种包括胎面的充气轮胎,胎面包括橡胶组合物,其包含20至90重量份/ 100重量份的溶液聚合的丁苯橡胶(phr),10至80phr 的聚丁二烯橡胶,其中0至20重量%的聚丁二烯橡胶是间同立构聚丁二烯橡胶,其包含间同立构1,2构型的至少70%的单体单元,其余的聚丁二烯橡胶包含至少90%的单体单元 顺-1,4构型; 和50至150phr预疏水化沉淀二氧化硅,其中预疏水化沉淀二氧化硅在通过用至少一种选自烷基硅烷,烷氧基硅烷,有机烷氧基甲硅烷基多硫化物和有机巯基烷氧基硅烷的硅烷处理之前被疏水化而被疏水化 。
