    摘要: The present invention relates to an aircraft tyre, the tread of which comprises a rubber composition based on at least one 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 statistically within the first diene elastomer, the ethylene units representing at least 50 mol% of all of the monomer units of the first diene elastomer. Such a tyre has a greatly improved landing performance, especially with respect to the wear resistance at very high speed.
