I also find it hard to see pucker as damage.
You hypothesize that carcass threads may be damaged, but is there any evidence of that? Any blowouts under the tape? Any hanging threads?
At least not in my experience.

This thread is for tubular tips and advice so I won't engage in any more hypothesizing.
But I do contend that pressurizing a tire OFF a rim will be more damaging than pressurizing a tire ON a rim. And I do have some anecdotal evidence - I once did an experiment where I pressed up a tire off rim to see how high I could get it and it exploded (casing failure) at 120 psi. I had had that same tire pressed up to well above 120 psi on a rim without explosive results.
Anyone attempting to replicate this experiment is advised to wear hearing protection.
