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