Abstract

Rubber compositions are disclosed for automobile tire treads. One or more SBR rubbers of higher than -40.degree. C. in Tg are combined with carbon black of specified N.sub.2 SA, DBP, .DELTA.DBP and .DELTA.Dst qualities. The resulting composition has enhanced tan .delta. at 0.degree. C. and 60.degree. C., breaking strength, breaking energy and abrasion resistance characteristics.
