Looking at putting a set of wheel off a 2018 e43. They are 20 inch wheels with an offset of 20 and 49. My offset on my 19 inch wheels are 34 and 48. They are pretty close so I am kind of confident they will function properly. My question will be the ride. Seeing as they are original AMG wheels maybe it will be ok?

Tires (if OEM) should be run flats, meaning sidewalls are harder than conventional tires. In addition sidewall will be a bit shorter 245/35-20 and 275/30-20 vs. OEM 19" 255/35-19 and 285/30-19, meaning they will be even harder due to a bit shorter sidewall. To compensate, if ride compliance is a requirement, might want to drive in comfort (vs. sport) mode all the time. The biggest issue I see is with the rear fitment. Assuming they clear rear calipers, rears will seat too much in vs. front wheels/tires (since E43's front wheels/tires will be almost 10mm out compared to CLS' stocks, this is good since stock is too much inboard). I would use 10mm rear spacers with longer bolts to make same visual change as the fronts.

You may need even thicker spacer (20-25mm). A 10mm spacer is not enough to make the rear to mach the look of the front for this setting. Do some calculation than you will find out.

If I remember correct, you using 285 in the back and final offset is 28 to match the front of 19.5mm offset. There for, he will need at least 20mm.
I just did: he needs exactly 15mm spacers in the rear to match the fronts, so that both front (without spacers) and rear (with 15mm spacers) will stick out the same 10mm vs. CLS' stock.
Its always good to have smart guys in your back pocket! I went ahead and purchased them and they look SICK !!! (good) lol. I do agree the rear need to be spaced out a bit so I will go get some hub centric spacers tomorrow if I can find them. I will probably put some wider tires on these when they wear out. My stock wheels looked a bit tougher being wider. Again thanks for all your help guys!!

Can not put wider tires on W213 non-E63 wheels - W213 wheels (except E63/E63S) are only 8" wide front and 9" wide rear. So the widest you can go is the W213 E43's stock 245/275.
FYI: H&R 15mm rear spacers P/N is DR 3055665 (or 3055665SW black) and to my knowledge ecstuning.com has/had the lowest new prices on them (check eBay too for a good price on clean used set). You will also need 15mm longer bolts, H&R P/N 1454302 (43mm), or 1454502 (45mm) or use MB's OEM S/ML/GLE/GLC 45mm bolts, MB P/N is 0009905407. For rear wheel locks, use MB OEM P/N B66470156.
For front, use your stock bolts with MB OEM P/N B66470155 locks.
I am putting this on a W218. These wheels are off a E43. I believe I can fit wider tires on these rims and after seeing them on the car I think this needs to be done. Too bad since they are brand new Pirelli run flats. So I had to use the lug nuts off the E43 because my lug nuts were too short. That being said I think I will need to order 60mm lug nuts after I add the spacers. Threemsbs I really appreciate your input here. Thank you!

In the US (base on the pic, you are not) and I assume should be elsewhere in the world, W218 E43 when equipped with run flats 20" wheels/tires, comes with 245/35-20 on 20x8 front and 275/30-20 on 20x9.
1. Fitting wider (255/35 or 255/30) front tires will require 8.5" wide rim, hence 245/35 is the widest than can fit on 8" wide rim.
2. Fitting wider (285/30 or 285/25) rear tires will require 9.5" wide rim, hence 275/30 is the widest than can fit on 9" wide rim.
3. Normally MB sedans, except S class, are equipped with 27mm bolts. If this is the case with this wheels, then you need 43-45mm bolts for rear 15mm spacers. However, if these wheels are already coming with 45mm bolts (like S class and MB SUVs), which would be deviation from what MB used on E-class before, then yes you would need 60mm rear bolts, H&R part number of which is1456002.

I am in the US. Just a Euro poser :-) Well thats a bummer! Would it just look odd if I went up a size because of the side wall? The reason I ask is these look stretched on as it is. Ordering the spacers and lugs today.
