An object of the present invention is to provide a rubber composition for a tread which is good in the balance between its wet grip performance and its chipping resistance. The rubber composition for a tread comprises 1 to 20 parts by mass of an ethylene-propylene-styrene copolymer and 60 parts by mass or more of a filler comprising a silica based on 100 parts by mass of a rubber component comprising 20 to 50% by mass of a butadiene rubber and 30 to 80% by mass of a styrene butadiene rubber, wherein an elongation at break of the rubber composition is not less than 300% in the atmosphere of 180° C. according to JIS K 6251: 2017.
