How many landings before an aircraft’s tires are replaced?
Some recapped tires will last for up to 100 landings, while others will last for less than that, but maintenance personnel and flight crews continually inspect tires for damage or wear. Additionally, visual ‘wear indicators’ on the tire itself offer ample evidence when a mandatory change is required.
