Just picked up a 2013 S4 Prestige and am looking for a set of 18" wheels to mount winter tires on. Can anyone tell me what's the min/max offset I can go with?

Just purchased 18 x 8" rotor reps off of ebay and they had an offset of 35mm. It's almost flush on my 2013 S4.

You can't go wrong on The Tire Rack. They will sell you wheels with the correct specs/offset.

I was lucky enough to find a set locally with snow tires (Hartmann HRS4s).

found a seller on craigslist with a set of 18's from an '12 A6 Offset is 39.
Think they'll fit?

I imagine you may have gotten something by now but for those looking for good resources...

Like Chigger says, TireRack.com has all the info you need. The may not specifically show offset for wheels they do not stock, they can tell you what the stock set up specs are and talk through other offset choices. Another site is WillTheyFit.com where you plug in the current/new spec to get instant results...
