TIRE TREAD COMPOSITIONS

摘要

Tire tread compositions are disclosed wherein the rubber component comprises: i) a first rubber component comprising about 5-15 parts of nitrile-butadiene rubber (NBR) per hundred parts of rubber (phr); ii) a second rubber component comprising about 43-95 phr of styrene butadiene rubber (S-SBR); and iii) a third rubber component comprising 0-47 phr of high cis polybutadiene (cis BR) rubber. The compositions may also include suitable amounts of other ingredients such as carbon black, aromatic oil, zinc oxide, stearic acid, sulfur, sulfur donor compounds, sulfur cure accelerators, waxes, antiozonants, etc.
