Abstract
Airplane tire tread (), having an axial width L, comprises a middle part () having an axial width Lbetween 50% and 80% of L and composed of a middle rubber composition, and two lateral parts (), positioned axially on either side of middle part (), each having an axial width (L, L) 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.
