Leaves out wheel offsets.
I saw this on a a random website but it is not confirmed.
This is more info, but honestly this wheel s*it has so many options, I'm probably going to end up visiting the local tire shop to get their input. On that note, I sent a request to the guys at Fitment Industries to see if they can add the EV6 to their site. Its a cool site because it can take your car and superimpose any wheels that fit it onto the graphic, which has got to be a HUGE help. I may have misspoken, because I am absolutely going to replace the wheels as one of my very first things I do. lol
You will need the offset, the wheel centre hole size and the PCD.
I have been looking for a while, but not found anything. Will wait till i get my own car and check it myself.
I find the above table strange as it shows 2 wheel combinations with the same wheel size, with a big differance in the offset (ET57 and ET48).
Best whipping a wheel off and it will be cast into one of the wheel spokes on the inside.
The PCD is also important, to get the wheel bolt spacing.
I had found this, but im not 100% sure if this is correct.
255/45/20.
5x 114.3 PCD.
Centre 67.1mm. ET50 for 8.5” Wheels.

Offset is just how far the mounting face of the wheel to the hub is away from the wheel centre line (in mm).
PCD is for the bolt spacing. The 5 means 5 wheel nuts / bolts.
Wheels and tyres are a mixture of Metric and imperial.
Wheels are in inches for width and diameter and offset in mm, yet tyres with the 255 and 45 being mm and the 20 being in inches.

Apparently its 20x8.5 +45mm 5x114.3 or something like that. I'm not buying anything until I take it to my local tire shop and let them help me with this. Besides, if THEY order the wrong thing, its on them and not me. LOL

Basically someone needs to pull off their bleepin wheels and stop guessin'. If my EV6 was here i would do it.. But I'm still rocking that Niro EV life... 4.1 mi/kw though..... I hope i dont miss it too much. 
I'm sure you know this, but others might not. The "45" is not mm. It's unitless. It's the ratio of the width of the tire (255 mm) and the height of the sidewall. In this case, the sidewall is 255 mm * 0.45 = 114.75 mm tall. Tire specifications just had to be designed by a committee, right? Three numbers, and one's in inches, another is in millimeters, and the last doesn't have a unit.
Yes, i was aware that the 45 is a percentage of the width, but it is also mm (45% of 255mm).
The main thing in this post though is the Offset or ET.
This comes into effect for wheel arch, caliper, suspension strut clearance. Some wheel suppliers will supply a wheel with the incorrect offset or ET, but will supply the wheels with spacers to take the wheel to the correct offset, but in some countries this would be illegal, and also invalidate your insurance.

20x8.5 +40 - +45 et would be the target.
Depending on how Aggressive you want the Stance to look.
+45 ET may be an issue, if the new wheel has too much Concave.
The inside of the wheel may make contact with the Brake Caliper.
But that will depend on the wheel style.
So, in my opinion,, +40 offset would be the safest bet.
I have Staggered Fitment,
20x8.5 35 ET
and
20x9.5 42 ET
The Factory 255 45 20 tires,
fit the wider wheels better, in my opinion.
And Yes,
The Factory 20x8 48-50 et wheels are 38 + lbs
The switch for me was a "No-Brainer" Move.
