From my experience the larger and lower pressure the tube the less cause there is for concern, I’ve also seen OEM Schwinn branded balloon tubes from the 1950s that held up fine but when I first began rebuilding old road bicycles I found that decades old tubes inflated to 75+ PSI could not be relied upon.

I grew up in Idaho and am also a firm believer in patching thorn punctures. I must be uniquely cheap as I save and reuse slime from otherwise unserviceable inner tubes.
