PURPOSE: A tire tread rubber composition for an aircraft is provided to improve abrasion resistance, heat resistance, and a reversion property by employing (n'-isopropyl-n-phenyl-p-phynylenediamine)-(4,4'-bis(alkylamino)diphenylamine) as an anti-aging agent. CONSTITUTION: A tire tread rubber composition for aircraft comprises 100.0 parts by weight of a base rubber, 30~60 parts by weight of carbon black, 10~30 parts by weight of silica, 0.5~1.5 parts by weight of 1,3-bis(citraconimidomethyl)benzene as a heat resistant improver, 1~5 parts by weight of (N'-isopropyl-N-phenyl-p-phynylenediamine)-(4,4'-bis(alkylamino)diphenylamine) of chemical formula (1) as an anti-aging agent, and 0.5~5 parts by weight of coupling agent.
