Document Type and Number:
Japanese Patent JP4088261
Kind Code:
B2
Abstract:
The present invention provides a rubber composition for a tread, in which wet grip properties, rolling resistance, steering stability, abrasion resistance and processability are highly improved in a balanced manner. Specifically, the present invention provides a rubber composition for a tread comprising (B) 30 to 120 parts by weight of carbon black and (C) 2 to 20 parts by weight of polyethylene glycol, based on (A) 100 parts by weight of a diene rubber containing 10 to 100 % by weight of styrene-butadiene rubber having a hydroxyl group in the molecular chain; wherein the carbon black (B) has nitrogen-adsorbing specific surface area of 175 to 300 m<2>/g, cetyl trimethyl ammonium bromide oil absorption of 155 to 250 ml/100 g and iodine adsorption of 150 to 330 mg/g, and the ratio of cetyl trimethyl ammonium bromide oil absorption to iodine adsorption is 0.85 to 1.20.
