it could have turned out real bad

Does she routinely hit curbs? My wife does and then curses when she finds bubbles in the sidewalls. I am lucky that she even looks at her tires though! She has had a slow rim leak in her car for two years and then two weeks ago, she bought all new Michelins. She then noticed that the same leaky tire was again low on air. She chalked it off on the leaky rim, but I checked it out for her anyway. I found a nail in the tread! Mystery solved - hopefully.
