Hey all. I'm looking for some new rims for my mini. I like 17". Will 17 by 7.5 fit alright? What about 17 by 8? What is the proper offset? Will a 215/45-17 fit or should I stay with the 205/45-17 that they recommend? I haven't put rims on a car in 15 years so I'm lost.

please help. I have looked at so many different websites in the last few days and they all say something different.
