I have been happy with my 17'' Audi wheels, with 225/60 R17 tires and they fit almost perfect and had about 1mm rub on the back very edge of the bumper that is hardly noticable (mostly on the inner lip portion) and it rubbed enough clearance on their own. 

I've been considering bumping up from 15" to 17" wheels as well and 235/60 R17 tires. I'm trying to figure out the fit. I measure from my current 15" tires to the bumper and I get 1.5" to the rear bumper and 2.0" to the front. It looks like it would be less with more lift in the suspension. I'm wondering why yours had a close fit but mine looks like it won't fit. My questions: What year is your EVC? Is your suspension lifted? Was your wear spot in the front or rear?

I love the look of those Audi wheels.
