When I patch a tube, does it need to be in a tire to "remain fixed"?
I mean: I understand an empty fixed tube will remain fixed if I keep it folded in a box...
But how about with air inside? does the patch need the pressure against the tire to remain steady?
I have pretty much never patched a tube,... so not really confident about the repair yet... Is it a good idea to ensure the quality of the repair by inflating the fixed tube and leaving it out there for a few days and hope it keeps its pressure?
