I recently patched my tube, and when I inflated it to 40 psi or so, I could hear popping in the tire from the pinches working their way out. And this is despite being careful by preinflating it before putting the tire back on.
I’ve had the same with new tubes as well. Just be careful when inflating your tube after installing the tire. This particular tear probably could’ve been avoided by preinflating the tube.
Or as you said, old tubes. Lots of factors, but a good tube will work a fold out unless it’s literally pinched between the rubber and rim.
