My mother's Mazda 6 just had Hakkapelliitas put on for winter, and they're rubbing a little bit in the right rear. I need to get spacers for her, probably 2-5mm and need to know if her stock wheels are hubcentric. I'm not home, so I can't really take the wheels off to see. Her car is a 2007 Mazda 6.

I would have searched, but I'm on my phone, so sorry for any repetition (if any).
