yes..i believe you could do 225 as well

 

Excellent. I built a pond, it's rather large, with my buddy for his dad and payment may be some RS4 rims

Plus they can get me a deal on tires, potenza's for probably about $100 off. Only problem is, I want 5 (one for the spare) can I just pick up one later and be fine?

 

sure.. you can always get a tire later on. They sell them individual usually.. check out places online if you cant go through your buddy..usually can find a decent deal

 

did you manage to get the 18" rims fit on your S4? i'm currently in a similar perdicament that the RS4 rims won't fit my S4, and wondered if you used spacers to fit?

 

Here you go guys, quality wheels (better then the ebay crap) & you will not need spacers
