You are coming up with reasonable conjectures as to why steel threads
might not work through the sidewall. The problem is the threads DID
work their way through the sidewall.

My point is simply that absent a manufacturing defect, the usual mode of
failure due to low tire pressure doesn't apply.

Rolling them at low pressure would flex the sidewalls more than they
are designed for.

But assuming no manufacturing defect, would not result in tire failure.
