I found a set of 20” OEM rims from a 2020 g550 and was wondering if the bolt pattern is still the same as 02-18 vehicles? They’re a pretty good deal and I’d like to swap out my 18” if they’ll fit.

Should work just fine....I had a '17 G63 where I put on 2020 G63 21" wheels and it fit great. In fact, with the offset it will even stick out a little further to be more flush with the fender.....

What is the offset on the w463a wheels? On my G55 the offset is 50mm.

For the w463a 21” G63 it’s 10” wide and a 32 or 33mm offset. Pushed it out 20ish mm or so on my w463 G63.

not sure if the 20” w463a wheels have the same offset as the g63

For the W463A G63 here's the specs:

20" 9.5 x 20 offset 35
21" 10 x 21 offset 33
22" 10 x 22 offset 36

I believe it's 5 x 130 bolt pattern.

Stock G55 wheel is 18" with width of 9.5" and a 50 offset.

my 2011 G55 wheels are 19” with a 50mm offset.

Yes, beginning with model year 2009 the G55 got 19" wheels...which look great but are sub-optimal in terms of tire options.

I put the 21” G63 wheels and tires on my 2017 G63. No issues. Used my factory tire sensors and wheel bolts.

How about the other way around? W463 20 inch rims (9.5 x 20H2 ET50) on W463A for winter use?

I don't know with total certainty, but I think you might end up with caliper clearance issues. You can swap newer wheels on the older body style, but I think the brake calipers on the newer ones stick out farther, so the +50 offset might hit them.

Good to know. Thank you very much!

I just installed G63 Wheels on my 17 G550 with 20mm spacers and they are perfect with 305/55/20. K02, I also installed a 2” spring spacer lift. Come out awesome.
