Welcome to Club Concorde - AIACC

May 2021

Between mid-April and May 5, 2001, the Concorde F-BTSD was sent to Istres to test a new tire developed as part of the supersonic refit program.

The NZG tire for Near Zero Growth was developed by the French company Michelin at the request of EADS, which wanted, for the Concorde main gear, to meet two essential criteria:


The tire must roll over a typical obstacle without loss of pressure or projection of debris. Two types of obstacle are imposed: a blade 30 mm high and a rod 3/4 "in diameter and 30 mm high.


The tire damaged in this way must demonstrate that it has retained sufficient structural strength to undergo various test cycles without loss of pressure or projection of debris.

The Michelin NZG tire perfectly meets the technical criteria requested by EADS.

The "Club Concorde" recalls to its impassioned philately that, from now on, the innovations are announced and illustrated progressively with their emission, in the page ' the philatelic products'. It is thus in real time that the Club informs you of the philatelic items
