Ian_C Posted August 29, 2014 Report Share Posted August 29, 2014 20x8.5 with 225/30/20 definitely doesn't sound like RS6 fitment - way too narrow. Quote Link to comment Share on other sites More sharing options...
Andy_Bangle Posted August 29, 2014 Report Share Posted August 29, 2014 (edited) Welcome to the forum John. IF they are genuine RS6 alloys, from a real RS6 then the tyres would be 275/35R20 and alloys should be 5×112, 38 Offset with a 57.1 CB (depending on MY) A 2012 A8 wheel is 5x122 with a 28 offset and 66.5 CB. I'd suggest they're fake alloys from a barryboy Golf or similar. Edited August 29, 2014 by Andy_Bangle Quote Link to comment Share on other sites More sharing options...
stang bang Posted August 29, 2014 Author Report Share Posted August 29, 2014 Cheers lads for your replyies ,what size wheels would be fitted to a s8 so that you get the full arch look ,I love the car but the standard se wheels don't do it for me ,cheers Quote Link to comment Share on other sites More sharing options...
Andy_Bangle Posted August 29, 2014 Report Share Posted August 29, 2014 (edited) The current S8 fitment has a stud pattern of 5x112, offset of 32 with a Centre Bore (hole in the middle) of 66.5. Tyre size is 265/40R20. Edit, Tyre size should be 265/40R20. Any wheel place should be able to sort you out if you want replica RS6 wheels. Here's an example from fleabay: http://www.ebay.co.uk/itm/20-VW-Touareg-2-5L-VW-T5-AMORAK-rs6-style-audi-a5-a6-a8-Alloy-Wheels-no-tyres-/251626492865?pt=UK_CarParts_Acc_Wheels_tyres_Trims_Car_Rims_ET&hash=item3a961b93c1 Edited August 29, 2014 by Andy_Bangle Quote Link to comment Share on other sites More sharing options...
stang bang Posted August 29, 2014 Author Report Share Posted August 29, 2014 Andy what is the difference between the rolling radius on the standard se and the size fitted to s8 ,so that the speedo reads the same or am I thinking too deep about it ,cheers john Quote Link to comment Share on other sites More sharing options...
Andy_Bangle Posted August 29, 2014 Report Share Posted August 29, 2014 Stick your tyre sizes in here: http://www.tyresave.co.uk/tyresize.html If you stick to OEM sizes then they should be okay. Quote Link to comment Share on other sites More sharing options...

Ian_C Posted August 29, 2014 Report Share Posted August 29, 2014 Fronts are 8.5 and rears 11 from memory. So you'd need two pairs fronts Quote Link to comment Share on other sites More sharing options...
