Tread of an airplane tire having axial width L, comprises middle part (3) having axial width LC between 50% and 80% of L and a middle rubber composition, and two lateral parts (41, 42), each having axial width (LS1, LS2) and a lateral rubber composition. The middle rubber composition comprises at least 50 phr of a first middle part diene elastomer (“FMPDE”), at most 70 phr of a middle part reinforcing filler (“MPRF”) and a crosslinking system, and each lateral part comprises at least 50 phr of a first lateral part diene elastomer (“FLPDE”), a content of lateral part reinforcing filler at least equal to the content of MPRF and a crosslinking system. The FMPDE or respectively FLPDE comprises ethylene units and diene units comprising a carbon-carbon double bond, which units are distributed randomly within the first diene elastomer, the ethylene units representing at least 50 mol % of all the monomer units of the first diene elastomer.
