I had the impression that Knotted has already "got this down" and that it was just a new tire combined with levers that weren't suitable for her particular rims that created the difficulty.
Ooops, sorry, I missed that part! I am glad she solved the problem. As women I think we are often discoureaged from doing mechanical things, and I don't think anyone should leave home without being able to change a flat and make at least minor emergency repairs.
