Although I'd want to run my hands over them for a close look for cuts, the ones in
Skippy's photo do look OK. There's no shoulder wear and the outer treads are complete around the visible circumference. To quote a well known phrase or saying, they have at least three landings left in them. One for the destination, one for the return flight and one spare in case of a diversion.
In some companies - especially those aiming for nine retreads - policy would be to change them; in others that only go for three they'll stay on until the outer grooves have almost disappeared. That's a cost decision though. The tyres are safe until well beyond the economic limits.
I notice that
Skippy123 didn't get a photo of the much more important brake wear indicators. Perhaps next time, eh?
That one from
vs69 was lucky. If he'd gone on any further he'd have been grinding his expensive sports rims down as well...
