So, I just got my scion xB about two months ago and it just has the factory hub caps on it and I'm wanting to put some rims on her. But, I'm not sure ho w many lugs it is. I don't wanna order rims and not be able to use them. Lol.. So if Anyone could help me out that'd be great. I'm new at this.. My friends have their scion's looking pretty badass and I'll feel stupid if I ask them. Lol
