An object of the present invention is to provide a rubber composition for a heavy-load tire having excellent low heat build-up when formed into a tire and excellent flowability of the rubber during vulcanization, and a pneumatic tire produced using the rubber composition. The rubber composition for a heavy-load tire contains a diene rubber and a carbon black; the diene rubber containing: a natural rubber; and a modified polymer obtained by modifying a conjugated diene polymer with a nitrone compound; the content of the natural rubber in the diene rubber being not less than 60 mass %; and the content of the modified polymer in the diene rubber being not greater than 40 mass %; and the content of the carbon black being from 30 to 70 parts by mass per 100 parts by mass of the diene rubber.
