Ironically, while driving to get new tires put on my car, I got a flat. I had to dig through all the crap in my trunk to get to the spare and I changed it without incident. I was careful to center the wheel and spin the lug nuts on with my fingers before giving them a final twist with the wrench. I intentionally didn't apply a lot of torque because the spare was coming back off in a few minutes anyway. I know the threads weren't crossed because, as I said, I ran the nuts all the way down with only my fingers. However, with the car on the lift, the nut just refused to come off and the stud snapped. I don't suppose this is something my warranty covers? I can put in a new stud, but if I don't have to, I'm at the age where I'm not inclined to crawl around under my car anymore.
