If you need to use a tool, there are some tire jacks that are designed to not pinch the tube. Park is one brand.
No, she pinched it with one of the bike levers actually, and I'm not sure at what point she did it (in addition to using the wrong tool, she's also 'heavy handed' and can break the unbreakable - but I still love her). I guess long story short is: I changed it and now understand the logic so it will be easier to do in the future.
