    • A tire tread composition is provided to improve wear performances of a tire by using wet masterbatch including raw material rubbers, silica, a silica coupling agent, oils, and carbon black. The tire tread composition comprises wet masterbatch containing 0.1-100phr of silica, 0.1-10phr of a silica coupling agent, 0.1-50phr of an aromatic oil, and 0.1-100phr of a carbon black based on 100phr of raw material rubbers. The silica serves as a reinforcing filler, has a surface area of 170±5 m^2/g and a moisture content of 6.0±0.5%, and contains at least 90% of carbon dioxide(SiO2). The carbon black has an iodine adsorption value of 90-120 mg/g and a DBP adsorption value of 130-140 cc/100g. The oil is an aromatic oil having a specific gravity of 0.95 or more and an aniline point of 60 or less.
    • 提供轮胎胎面组合物以通过使用包括原料橡胶,二氧化硅,二氧化硅偶联剂,油和炭黑的湿母料来改善轮胎的磨损性能。 轮胎胎面组合物包含湿法母料,其含有0.1-100phr的二氧化硅,0.1-10phr的二氧化硅偶联剂,0.1-50phr的芳香油和0.1-100phr的炭黑,基于100phr的原料橡胶。 二氧化硅作为增强填料,其表面积为170±5m 2 / g,水分含量为6.0±0.5%,含有至少90%的二氧化碳(SiO2)。 炭黑的碘吸附值为90〜120mg / g,DBP吸附值为130〜140cc / 100g。 油是比重为0.95以上,苯胺点为60以下的芳香油。
