The invention discloses a tread rubber composition with a majority of renewable components. A tire component is formed from a rubber composition comprising a majority weight percent of renewable material. A rubber composition comprising, based on 100 parts by weight (phr) of elastomer, a blend of at least two rubber elastomers selected from the group consisting of: from about 40 phr to about 50 phr of polybutadiene; up to about 35 phr of a styrene-butadiene copolymer; up to about 45 phr of natural rubber; a bio-derived resin material; and a bio-derived filler comprising silica and a carbon black filler. The carbon black filler is at least partially derived from a bio-based feedstock prior to its addition to the rubber composition. The resin and silica are also derived from renewable materials.

    本发明公开了具有多数可再生组分的胎面橡胶组合物。由包含多数重量百分比的可再生材料的橡胶组合物形成的轮胎部件。基于100重量份(phr)弹性体,橡胶组合物包含:至少两种橡胶弹性体的共混物,所述橡胶弹性体选自:约40 phr至约50 phr聚丁二烯;至多约35 phr的苯乙烯‑丁二烯共聚物;至多约45 phr的天然橡胶;生物衍生树脂材料;以及生物衍生填料,其包含二氧化硅和炭黑填料。炭黑填料在其加入橡胶组合物之前至少部分衍生自生物基原料。树脂和二氧化硅也衍生自可再生材料。
