19x8.5 front and 20x10 tsw rascase rims
 

I just bought these rime for 300 and i was wondering what offset should I have on front and rear. And also what size tires should I run.

so you bought 19s front and 20s rear?

just google those wheels and they dont look half bad

but the double staggered, as they call it, is nuts in my opinion

Wait! You already bought these and you're asking what offsets you should have? First of all, it would be helpful if we knew what you are driving.

I agree. Running two different tire sizes is a bit iffy.
