Airplane tire tread (2), having an axial width L, comprises a middle part (3) having an axial width LC between 50% and 80% of L and composed of a middle rubber composition, and two lateral parts (41, 42), positioned axially on either side of middle part (3), each having an axial width (LS1, LS2) between 10% and 25% of L and each composed of 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. FMPDE is a terpolymer of ethylene, of an α-olefin and of a non-conjugated diene. The FLPDE lateral rubber composition of each lateral part comprises at least 50 phr of a first lateral part diene elastomer, a lateral part reinforcing filler content at least equal to the MPRF and a crosslinking system. The FLPDE is a terpolymer of ethylene, of an α-olefin and of a non-conjugated diene.
