RUBBER COMPOSITION FOR TREAD AND TIRE HAVING TREAD MADE OF THE SAME

摘要

Disclosed is a rubber composition for treads, which contains 0.5-10 parts by mass of an alkylphenol-sulfur chloride condensate (B) represented by the formula (B1) below, 0.5-6 parts by mass of sulfur (C) and 10-100 parts by mass of silica (D) per 100 parts by mass of a specific rubber component (A), for attaining both low heat generation property and adequate breaking strength. Also disclosed is a tire having a tread which uses such a rubber composition for treads. (In the formula, R1-R3 each represents an alkyl group having 5-12 carbon atoms; x and y each represents an integer of 2-4; and n represents an integer of 0-10.)
