My tweenage 24" MTB experience with them 30 years ago was that if you don't keep your tire pumped up hard they let it squirm and shear off the valve, which probably won't be a problem for a boring responsible adult.
True. I think the tire liners work best if you are near or at your max pressure. For those who know better and run lower - the tire liners can cause problems - especially if you ride hard. The fatter the tire, the lower the pressure the harder you ride - the more likely you are to have problems with tire liners. Pump up a road or hybrid tire and ride it at <150 watts and you'll probably be fine.
