Abstract:
An object of the present invention is to satisfy both of the low heat build-up property and strength at break. The present invention provides a rubber composition for tread comprising 0.5 to 10 parts by mass of (B) an alkylphenol-sulfur chloride condensate indicated by the formula (B1): (wherein R1 to R3 are same or different, either is an alkyl group having 5 to 12 carbons; x and y are same or different, and either is an integer of 2 to 4; n is an integer of 0 to 10), 0.5 to 6 parts by mass of (C) sulfur, and 10 to 100 parts by mass of (D) silica, based on 100 parts by mass of the specific (A) rubber component comprising, and a tire having tread using thereof.
