ABSTRACT:
A predominantly styrene-butadiene copolymer rubber (SBR) tire tread compound may be reinforced with a special high structure carbon black designated herein as a N103, having a relatively high volatiles content (as indicated by its iodine number), and a superfine particle size smaller than about 20 nanometers (nm), a DBPA greater than 120 cm.sup.3 /100 g carbon black, and an I.sub.2 No in the range from 130-160 mg/g, in an oil extended tread compound in which there is at least 30 parts of processing oil per 100 parts of rubber; the presence of this N103 black in a major amount relative to the total amount of high structure black, is essential.
