I've got a 2013 Q7 Prestige with the stock 21" Speedline triple-spoke wheels. They are 21"x10" rims with a 44mm offset and the stock 295x35R21 tire size.

What sort of wheel options are available with a low offset close to what I have? Most wheels I'm finding (stock Audi / VW / Porsche) are in the 53mm-60mm range on top of being much narrower. I'd like to find something VAG OEM if possible (I don't want especially custom-looking wheels if I can help it), but I'm willing to entertain options.

My current winter wheels are stock 7-spoke 18" rims (ET53) with some narrower tires, and they push the tire edge a full 1.5" under the fender.

Thank you, Chris

vehicles with OEM 21's got wider fender flares and steering bump stops on em, all VAG wheels smaller than 21in will not have that offset because they all went on vehicles without those and are using stock offsets for those sizes..

wheel spacers is about your only recourse for OEM wheels if you want em to stick out as far as your 21s do

Hey Chris,
I to have the same set up with Graphite/Titanium color.
I found these sites (links below) to be quite helpful in figuring out tire difference.
I to would like to find a nice used set of 18's for winter months, but I live in NC and get very little snow there, so I am not as concerned. I travel around upper mid west, northeast so that is why I would get them.
I really wouldn't mind getting ahold of the same wheel in a 19, like the A4 A6? And use an adapter, because I love the look of these wheels!

I cannot find a matching size tire for the stock 21, in an 18 A/T.
Question: If I get a different size, is there a way to notify the car via VCDS of a different size tire being applied?

dont matter if you go a different size as long as all the wheels are the same.. there's 2 stock OD's on the Q7.. one for the 21's and one for everything else.. you should be fine going to the <20in OD.. it'd be smaller and your speedo would read slightly high which is how all manufacturers do it.

If you change size so dramatically your speedo is way off, you can adjust it slightly w/vcds.. but not alot.

https://tiresize.com/calculator/ should help you see how much difference the wheel sizes will have on speedo

hanks on the VCDS!
I have those calculators book marked for easy reference!
I have a friend (dealer) that has a set of 18 aftermarkets (stock look) in good condition for $250.
Then I would need tires for them. Trouble is, I cannot find the A/T version, yet, that is close enough to stock.
I would also have them painted to match color with ride.

Will a 265/50 -r20 work instead of my 275/45-r20s?

Those are almost 18mm (~3/4") taller. You would want to search to see if anyone has that tall of a tire without rubbing; also it will mess with your speedo and odometer without some adjustment.
