Abstract

PURPOSE: Title rubber composition which provides tires exhibiting excellent running performances on snow-covered or frozen road surfaces and wet road surface, prepared by compounding three different specific stock rubbers, an extender oil having a specific viscosity-gravity constant, carbon black, etc.
CONSTITUTION: A tire tread rubber composition is produced by compounding (A) 100pts.wt. of a rubber stock comprising (a) 10W60pts.wt. of natural rubber or synthetic isoprene rubber, (b) up to 50pts.wt. of diene rubber and (c) 60pts.wt. of diene copolymer rubber (the sum of a, b and c being 100pts.wt.); (B) 30W 80pts.wt. of an extender oil having a viscosity-gravity constant (V.G.C.) of 0.80W 0.93 as determined from the equation, wherein CP, CN and CA are percentage of paraffinic carbons, a percentage of naphthenic carbons and a percentage of aromatic carbons, respectively; carbon black; sulfur; an organic accelerator; etc. Then, the resulting rubber composition is vulcanized at 135W200°C for 5W100min. thereby to produce tires having physical properties shown in the table.
