Authorized service centers for Michelin Aircraft Tire are running an incentive program called “Upgrade to Michelin,” which offers an instant 20-percent rebate to customers who convert all the main landing-gear tires on their aircraft from a competitive brand to Michelins. Add in nose landing-gear tires, and the discount rises to 25 percent off the whole purchase of Michelin tires. The offer is available only through authorized service centers in the Michelin FBO network.
