D4 A8/S8 22" Wheel Test Fit
So I'm in the market to buy a 2015 S8 and I have a set of 22" wheels that came off of a Mercedes W222 S63. I'm looking to test fit on a members A8/S8 in the Boston area to make sure the wheels fit. I've done some due diligence already; Online Fitment Calculator and Checked with the Wheel Manufacturer. All seems well as if the wheels will fit, but I'd like to test fit the wheels on a vehicle for 100% transparency. Looking to only mount up the front and rear wheel on the car to check for clearance and the look on the car. If you have free time and are in the area, please let me know.
Wheel Specs: 5x112
Front: 22x9 ET 32
Rear: 22x10.5 ET 40

Tire sizes
You cannot! use the same size tire all around as they will NOT be the same height if they are installed on different WIDTH wheels!
And, just an observation here but I am willing to bet no one is going to let you guinea pig there car to check wheel figment for a car you don't even own!!!! Who the heck has time to do that? Only a damn good friend or family member........a complete stranger????

245 Front and 295 Rear. Fronts are 22x9 Rear are 22x10.5 so 275 won’t work. If I ran Factory wheels same width then 275 would be fine.
@Stevreddy- I would do it for someone if they asked and had the time. Stranger yes, but I look at it as a networking opportunity. You meet a fellow member in person, shake hands, strike up a conversation, you never know, you may know the same people through other people. Strangers are only strange because they haven’t met yet. So you may not be the type of person to do this for a person in need because it inconveniences you, but everyone doesn’t feel the same as you. If it were me, I’d have no problem helping a fellow AW Member out.

I'm actually going to have 10.5 front and rear, I just need to confirm the rear wheels fit to get the front made to spec. The current setup is how I acquired the wheels from the previous owner.

Some do a stagger for looks where they use a wider rear wheel but still hold the tire width. If doing that and dont use a square tire set up (as in, differing widths and then adjusting aspect ration to try to hold diameter constant), you have to be sure at the same time to hold the dynamic tire running circumference spec to the 2% or so (be sure to check whatever the spec is...) so quattro center diff doesn't get stressed and fail.

I went from owning an S63 to an S8 and I used the 22's off my S63 on the S8. As long as the diameter is the same you should be fine. I had 22x9.5 +35 and 22x10.5 +45 in the rear. I was running 245/30/22 in the front and 295/25/22 in the rear with no rubbing issues at all.
