Abstract
Airplane tire 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 L 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) 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 diene elastomer, a reinforcing filler and a crosslinking system, which first diene elastomer 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.
