Tire tread composition
Abstract:
Tire tread compositions comprisinga) 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.
