In above picture, the middle image is the “rim too narrow / tire too wide” extreme example. The left image is the normal install. The image on the right is the “stretched” tire, which some people find cool, but I think stretched tires look retarded.
And for text book tire widths vs rim widths, a Google search for “tire rim width chart” will find charts like these two, showing recommended tires sizes for rims:

I guess some S6’s come with 255 wide tires. This fitment info is from Google search for “2010 S6 offset”. You can see the OEM rims jump from 8.5" wide to 9" wide when going from 255 wide tire to 265 wide tire:

Thank you VERY much! This has been extremely insightful and the mighty tool of Google is key when you know which words to search up. Awesome stuff - again, thanks a lot. It’s greatly appreciated.
And regarding wheel spacers, just so ya know, wheel spacers do not increase offset number. A higher offset number sends the rim into the center of your car, and a lower offset number sends the rim away from the center of your car. In other words, wheel spacers decrease offset number. With your offset of 40, for example, when adding a 5mm wheel spacer, that would change the offset to 35, which probably pushes the rims and tires to pretty much touching the fender lip.
I’m confused then. I was under the impression that offset was from +X to -X with 0 being dead center.

With wheel spacers, wouldn’t the offset increase since in essence the wheel is being pushed further from the vehicle?
EDIT: After researching, I see your point. Would a 40 offset look too odd on the S6?
Happy to help. The Google references are not only for your specific question, but also to beef up this thread and help future readers with different fitments.
And yeah when people have “more offset”, it usually means “lower offset number”, so that’s confusing, but what can ya do, right.
So now that you have a better understanding of offset, it may help to re-read this thread, to see the set ups people have mentioned. “BlackS6” had Reply 24 in this thread with some awesome pictures. He was running 255 wide tires and 35 offset. However, he also rolled his fenders.
And if you don’t know what “rolled his fenders” means, then Google “fender rolling”. Haha. Essentially you pinch the inside edges of the fender all along the edge of the fender, to give you just a little more rim/tire room.
I believe this is compugeek5150 looking at BlackS6’s Reply #25 on: January 08, 2016, 11:58:16 AM
I think we can all agree that the 40 offset will look good.
The difference between this ET40 and factory ET52 is basically going to see the rim’s lip moving 12mm closer to your fender (52-40). In other words, the rim’s lip moving 1.2cm closer to your fender, or, about half an inch closer to your fender. You can go check yourself by putting your finger between the rim and the fender. Good to go.
And if you’re eyeballing this with your finger, consider that unless you’re SURE sure that you have factory rims (or unless you’ve seen the offset stamped on the back of the rim), then you might just have replicas with a different offset than OEM. Or, you may have aftermarket wheels with Frankenstein’d center caps that just look factory. Again, offset might be different on aftermarket wheels that look factory. If you see any pictures of my wagon on here, then those wheels are not factory. They just look factory (factory Audi front of cap stuck on aftermarket caps).
murphenur says he’s running a 35 offset, and it fits under his air suspension. Good to go.
He is talking 18" rims, but remember that overall diameter of tire stays the same regardless of rim size (sidewall height changes), unless you’re deliberately going away from a factory tire height. Most people keep the same overall diameter, so that your setup will be compatible with your full sized spare tire, and your spedometer.
Here’s an example of custom OEM-look center caps, made for lightweight Enkei RPF1 wheels. Offset not OEM. So if you were eyeballing these on your car and thinking about what would fit compared to these “factory” wheels (like if they came with the car and you assumed they were OEM), then you’d be wrong to assume factory fitment when eyeballing. Ya know? Some day soon I’m gonna create a thread for these over in the A4 section:

That’s all good information and I love those caps.
Attempt to revive this thread, see what people are rocking these days, as most links here are dead by now. Anyone running 275/30 on 20-10 ?
I ran 265/30 on 20" in the rear with no problem, I now rock 285/30 20" in the rear and it rubs a little on the fender lining both on 10" wide rims with ET35.
But it seems like it can be fixed.
I am lookin at some JR28 10" ET40, and scared it will rub 275/30s, and some R series R9 10" ET50 which i reckon should fit nicely. Since you say in the rear specificly, are u running staggered? Or did u use same in front, without rubbing on both widths?
Yes, I run staggered, so 245/35 20" 8.5" wide with ET32 in the front.
willtheyfit.com is a great place to look and compare.
What you are looking at vs. what I have.
I have 275/30 r 20x10 on my car, lowered with HnR springs
You recall the ET? And no rubbing:)? This is like, exactly what I am looking at so:)
Nice, the 20s certainly suit the car, I believe the et is 35 all round.
The previous owner put these on and I can’t imagine the car with smaller wheels
I have 15mm spacers on the rear and none on the front
The only rubbing I have is when the suspension is compressed but that is likely due to the lowered set up
I plan on raising the car to address this but other than that no rubbing anyhere else
