FIELD: automotive engineering.
SUBSTANCE: pneumatic tire has tread in which a vulcanized rubber composition is contained, comprising per 100 parts by weight of elastomer (phr) (wt % per 100 elastomer wt %): (A) from about 50 to about 90 phr polymerized in solution styrene-butadiene rubber having glass transition temperature (Tg) is from -65°C to -55°C; (B) (B) from about 50 to about 10 phr of polybutadiene, wherein cis -1.4 content is greater than 95 percent and Tg is from -80 to -110°C; and (C) from 30 to 80 phr combination of oil and terpene-phenolic resin, wherein Tg is over 100°C.
EFFECT: improved wear resistance, rolling resistance and tire slippage on wet road.
