whoa whoa whoa..... I just ordered 18" wheels for my car...... is that something I shouldn't have done........ my 1.8t is quattro......

 

nononononono... ok... the only time you will have a problem... is when you have staggered rims... like 16" in the front and 17" is the back... dont worry your car will be fine as long as you have 18"s all the way around...

 

gotcha...... sorry for the ignorance

 

actually ,i saw a set of those ,they were anadized a dark smokey color,they made the car look f'n way cool.the web seemed to start at the edge of the rim though.

 

i think they are going to look amazing on my car...

heyheyhey.. dont worry about it... you didnt know... just like i didnt know how to roll my fenders...

 

I am well aware that it is the diameter that matters... I said that in my post.
My point, is that you have to find a tire with the same circumference...
a 225/40/18 up front... and maybe a 245/35/18 in the rear? or a 255/35/18? I dunno. Just use tirerack.com specs and find two tires that will fit... that will have the same diameter.

I run a staggered setup... sort of. Just different offsets... I run 17x8.5 all 4 corners, with 235/45/17's.

 

I rolled my fenders with a special tool used for it, but I think what headshok said would work to. Just make sure you heat up the paint so it does not crack.

I don't think you will have to roll your fenders with 17's though. How low are you? What suspension are you running?

 

right now im sitting on stock... but im not puttin on my rims till i get my h&r coilovers... slammed... how ever low that is...

 

Who says you need to roll your fenders? I had 18x11 on my 944 and with the correct spacers there was no need to do anything of the sort.

 

Yeah, but that was your 944 bud... haha I cant believe you are using that as a comparison!
It doesnt take much before you have to roll the fenders on an a4... I run 235 45 17s and I gotta roll them...
