What other Mercedes vehicles share the same wheel bolt pattern as the R?
For the R, Parts listings specifically are 8J x 18 H2 ET 67 (255/55 WR 18 105H); 8J x 19 H2 ET 67 (255-50-R19 103W), and the 8.5 J x 19 H2 ET64 (front) and 9.5 J x 19 H2 ET 66 (rear).
Europe shows a 8.5 J x 20 ET 60. (265-45 R20).
I had a devil of a time finding a used set of the sexy 20 or 21 inch AMG wheels (a-la-R63) (which are staggered sets usually on ebay) so settled on a set of 18" 5 twin-spokes. (the 8J x 18 ET67 with 255 55-R18s) Of course there is the flatter looking 5-spoke 19" AMG wheel 8.5J x 19 ET 64.
Then there is the 255-50-19 Situla, the 255 55 18 10-fin, the the 255-50-19 five spoke with small 2 chunks on the rim and between the spokes, the beautiful and expensive 265 45 R20 Alanz (8.5 J x 20 ET 61).
Then there is the base-wheel on early models, the 7 spoke - 7.5 J x 17 ET 56 with 235 65 R17s...
The order for the specs above is
1. Internal rim width in inches
2. Code letter for height and contour of rim flange
3. Code for one-piece drop center rim
4. Rim diameter in inches
5. Rim profile at outside and inside with hump shoulder
6. Wheel offset.
So for 6 J X 15 H2 ET49
1. is 6
2. is J
3. is X
4. is 15
5. is H2
6. is ET49

As regards fitting wheels from other model Mercedes, the answer is probably none of them.
You really need to stay with OE wheel widths and offsets and tire sizes, and it would be pretty surprising to find another model with same specs as your R.
And, I can promise you wheels from another model will look dumb.

The GL, ML, and R are all built in the same Alabama factory.
There are lots and lots of common parts.
Besides engines and transmissions, there are next to zero parts in common with any other models, i.e. those made in Europe like the S-class.

Nevertheless, I purchased 18" wheels from ML350 (MB Part number A164 401 03 02) with almost new OEM Conti 4x4 tires and after having them nicely balanced, the mechanic had a problem mounting the wheel. It turns out that the bolt appeared to short. Do I simply need longer bolts? He did not check rest of the wholes so I am not even sure if the wheel will fit. I called the MB service before the purchase and they told me that it should fit
and now the bolt issue... 
Any help is appreciated.
Thank you!!!!
Here are all the numbers from the back of the rim:
A164 401 03 02
B6 647 42 88
8j x 18H2 ET80
SI 7 Wa
They made in Mexico and I am attaching not actual picture (I borrowed it from other sites)

Unfortunately ML wheels have, from what I've been told and seen, a unique offset for the 2006-2010 ML's only.....60mm I believe....I have been looking for a second set of wheels for my 08 ML and not found any other class, so far, that will directly bolt on.
Are you sure those are 18 inch? I've seen that exact photo on eBay listing them as 19 inch.
If they're 19 inch, I'm interested.

the picture for the posting from the 19" eBay listing.When you mention the offset, does it mean that it will not fit after all? Using longer logs, studs, bolts or screws
would not do the trick? And if they do, do you think the bolt pattern is the same?Any help is appreciated.

I have seen other threads where people have used spacers to accommodate different offsets, but I have no experience. If it's not a direct fit, I'm sticking with factory.
I would contact Luke at Tirerack.....they are very helpful and extremely knowledgeable...keep us posted.
Offset matters because it basically tells how far is the wheel's "mounting surface" (or whatever it's called) from the center of the wheel. The smaller the offset, the closer is the surface to the center of the wheel. Ie. if you go smaller offset than your current wheel and if the wheel is the same width, then the wheel will come more out. And if bigger offset, then the wheel will go more in, which means it may touch suspension, brake calibers etc.
Small change with the ET doesn't usually matter (it's measured in millimeters so you get the idea of the difference), and actually if you go wider wheels, you typically need to have different ET to fit wheels properly. If you go wider wheels, you actually should have smaller offset than your current ones to get the same clearances to suspension parts.
You can actually calculate the difference in your wheels.
Your new wheel: 8j x 18H2 ET80 (which has BTW huge offset, you sure it's ET80?)
OEM is ? but let's take one of mentioned 7.5 J x 17 ET 56 (I supposed you were up-sizing from 17 to 18 inches)
New wheel's inner edge will be about 30 mm more inside than the old one. This sounds quite a lot, if these numbers are from your old and new wheels, I would be concerned if the new wheels (or tire) would hit some suspension parts etc. Of course if your OEM wheel is e.g. 8J x 18 H2 ET 67 then the difference is only 13 mm which is not so much anymore (about half an inch), but still sometimes causing problems.
Anyway, the offset doesn't matter in your bolt length problem, so either the new wheel is thicker or maybe they tried to use spacers (to adjust the offset, ie. to get wheels more out) and that's why the bolt is now too short? (I wouldn't personally use spacers but rather find more suitable wheel)

I consulted with Phil from radusadirect.com. He was very helpful. He said that the MB uses longer (not larger) bolt lugs from 18" and higher. That is my case. You are correct that the wheel is thicker ion the middle which naturally needs longer screws. I am waiting for the lugs to arrive and as soon as I have update I will post it here.
BTW all numbers that I previously entered are from the wheel stamp. Again, this is a OEM wheel from a ML.
