I'm guessing your existing wheels' ET plus your new ones but heres my best guess at where a straight swap will come out -

What website did you use for this? Thanks

ummm. suggest "www.willtheyfit.com". (Its printed across the picture ;) )

that'll be it! Ignore the suspension shown on the drawing its only to show the side that it is on rather than the position itself although the 2 lots of wheels and tyres will be spot on - the new wheels will project 11mm out more than the old ones and 27mm more inwards, and that could be your problem

Lol :ROFL: only just got up was on half nights last night. My eyes mustn't be working yet ha.

i Used to run 10x20 ET35 with 255/35/20 front and rear on my A8 with KW2. I'd say thats just perfect stretch... Wider tires make it look like truck/tractor :)
No rubbing or scraping even when car fully loaded:)

Cheers for that I'm trying them Thursday so will update then with pics :)

They fit, no rubbing and no catching the suspension arms. Happy days, now to by some tyres :)

While I was at it i dropped the oil and changed filter, changed spark plugs and air filter.

Thats a result :) have you checked it on full lock both ways?
I'd note how much space you have too if you can as the new tyres will be straighter onto the wheels than the current stretched narrower ones +++

Yes full lock both ways and no problem +++

There was quite a bit of room so hopefully new tyres will be ok. Still not sure what size to run. My mate runs 245/35/20 on his RS4 and they look and handle great might go 255/35 if I can. :)
