They might eventually, since they do rub against the stainless on the body, but I wouldn't expect it to happen any time soon. I think some folks have had issues with the ring getting deformed in the process of trying to remove/clean it. If it gets deformed, it can be tricky to get it back into shape to work properly. I have found that it does help quite a bit to remove the ring and clean it regularly. If I don't clean mine every couple of weeks, it will start to lose some grip. Once cleaned, it's been as good as new, so far. I've had my ELA since May and, after a good cleaning, the ring works just as it did when I first got it.
