TIRE TREAD COMPOSITION.

摘要

Tire tread compositions comprising: a) a first rubber component comprising about 60-90 parts of styrene butadiene rubber (SBR) comprising less than 20 percent by weight of styrene, per hundred parts of rubber (phr); b) a second rubber component comprising about 10-40 phr of nitrile-butadiene rubber (NBR); c) 30-80 phr of carbon black; d) 10-20 phr of silica; e) 1-3 phr of a silane coupling agent; and, optionally, f) a third rubber component comprising about 10-30 phr of a high cis polybutadiene rubber (cis BR). The tire tread compositions provide tires with excellent wet traction and low rolling resistance.
