I realize there may be a thread that answers this, but I have searched and thought it would be easier to just ask the question. I have a 2001 A6 Quattro2.8L with the factory 16" "wine glass" wheels with 205/55-16 tires, and have located some 18 X 8.5 non-factory wheels with a +32 offset and 225/40-18 tires. I'm looking for wheels and tires that will be a bolt-on, no modification replacement - I am not interested in rolling fenders, cutting the inner guard, etc. Any comments would be great - thanks.
