Abstract: Tire belt comprising a rubber composition based on at least one isoprene elastomer, a reinforcing filler, a crosslinking system and an antioxidant agent, characterized in that said antioxidant agent comprises a 4,4?-bis(alkylamino)triphenylamine corresponding to the formula (I): in which R1 and R2, which are identical or different, each represent a linear or branched alkyl group having from 1 to 12 carbon atoms or a cycloalkyl group having from 5 to 8 carbon atoms. Such an antioxidant gives the belt of the invention a better long-term resistance to fatigue and to crack propagation.
