These are -12mm offset wheels with 1.5" spacers up front and 1" spacers in the rear. If your +12mm then yours would essentially be 24mm further in than these pictured.. Tire size will play a small role but not much.
**NOT MY PICS
*EDIT: If you haven't bought wheels yet I would consider starting with a negative offset wheel to eliminate the amount of spacer you have to use. Just my two cents.
