In fine condition, with worn tread and expected wear. Michelin took over as the sole supplier for Space Shuttle tires in 1989 when the company purchased BFGoodrich, which had manufactured the tires since the first Shuttle launch in 1981. Michelin continued to improve upon the BFGoodrich design, and the first set of Michelin Air tires were used in 1995.
Provenance: The Spaceflight America Museum and Science Center in Prince Frederick, MD, where patrons were invited to touch the tire.
