A rubber composition for coating a fiber cord includes a diene rubber, a carbon black, and a nitrone compound having a carboxy group; the diene rubber includes a natural rubber and a styrene-butadiene rubber and/or a butadiene rubber, wherein a content of the natural rubber in a total of the diene rubber and the nitrone compound is not greater than 65 mass %; a content of the carbon black is 40 to 67 parts by mass per 100 parts by mass of a total of the diene rubber and the nitrone compound; and a content of the nitrone compound is 0.1 to 10 parts by mass per 100 parts by mass of a total of the diene rubber and the nitrone compound. Such rubber composition for coating a fiber cord has excellent low heat build-up when a tire is produced and excellent adhesiveness with carcass cord.
