I drove myself crazy trying to find a cost effective staggered set-up and settled for 20x8.5 all around with 245/30/20's. My car is lowered via SDS, looks great, no rubbing, no issues.

Hello, I also have some questions on making 20 inch wheels flush on a 2011 E550 4 Matic. I have 20x9 wheels front et 40 offset and 20x10 rear with et 42 offset. I have 235/35/20 front tires mounted on the wheels and have 275/30/20 tires that have been ordered for the rear.
I'm sure that I will need at least 5mm spacers in front but was wondering is 10mm spacers would work on the front since that would give et 30 offset. The 5mm spacers would give a et 35 offset.
It looks like I would have to keep the rears the way they are but was wondering whether the 275/30/20 tires with the 20x10 wheels et 42 offset will be a problem or rub.

12jbat, I'm not sure on the fronts, but your rears with those tires and offsets you should be fine with no rub. Hopefully ThreeMBs will chime in..

For front, I would try 5mm spacers first. If it still rubs, then 10mm will fix it for sure. However, with et30 a 9" wide wheel will be passed front fender's edge of non-AMG W212 (et35 is as aggressive as one can get for front 9" wide wheel of E550/E350). As I mentioned before, 8.5" wide wheel would be a better - safer and guaranteed - fitment for your car when used with 235/35-20 front tires.

S212 350cdi-4-matic `11 "AMG" // C207 350cdi ´10 "AMG"
I just bought s212 4-matic and I wonder can I use my old car wheels?
My wheels spec. are 20"x10" offset 40 and 245/35/20 tyres.
I think rear this setup is fine, but what you say front are they too wide?

2011 E350 P1 sport package with panoroof
Hello,
Im looking at the tire sizes that you guys used for 20 inch wheels and I'm still not sure what sizes to use for sure.
I have a 2011 E550 4 Matic sedan and I am looking for tires to go on my wheels that are 20x9 with +40 offset front and 20x10 with +42 offset rear.
I have 4 brand new Goodyear Eagle F1 in 245/30/20's that I had for spares from another wheel setup I had for a different vehicle but I am having trouble finding the matching 285/25/20 tires to go with the front tires. I know at one time someone had a few pairs for sale but they are no longer available. If anyone is interested in these tires I may sell them because it look like I should get a bit thicker side wall.
I was considering using the 235/35/20's in front and 275/30/20's rear but was concerned about rubbing in the front. Others have said this shouldn't rub so I think 235/35/20 in front should be ok. I wasn't sure about 235/35/20 for a 20x9 front wheel though. I know 245/35/20 will rub.
I'm looking to purchase tires as soon as possible so any suggestions would be appreciated. I want to make sure I get the right tires.
Thanks!

I was being told to using 235/35/20 front, and 255/35/20 to avoid rubbing issue while driving over 80mph and still get very comfort. Therefore, i have this set up, and absolute right choise...

Whats up guys, i have a 2011 w212 E350 4matic and i was told that with a custom offset specifically for the car i could run front 245/30/20 and rear 285/25/20 without rubbing. If thats the case why cant i run a rear 275/30/20 without rubbing?

I have a similar setup.
As the roads in my country not excellent as in Europe, I will not lower the car.
I went with
Giovanna MECCA FF, R20 8.5 ET35 rear and front.
Now I have 4 tyres Lexani 225/30 ZR20 85W XL LX-SEVEN.
The stock tyres are 245/45/R17.
My questions is that if I will change tyres, what will be my best option?
- Keep the same tyres dimensions: 225/30 front and rear.
- Change only the height from 30 to 35, to compensate for the fact I'm not lowering the car but also to give it a better look.
225/35 front and rear
- Keep the height to 30 and increase the width to 245 for front and rear.
245/30 front and rear
- change both 245/35 rear and front
- Keep the front to 225/30 and change the rear to 245/35
I would like to improve the look, protect a bit more the alloy wheels.
Thanks for the help
PS: I don't have a better picture for now, sorry.

For staggered tires you need to go to tire manufacturer side and find rpm to compare. Experience shows that 3% difference is acceptable, but more will disable CC and eventually ESP will start flashing.

Rubbing bottom of shock housing
Hello! I just got 20” rims and tire put on yesterday, I’m not getting any rub from the wheel well but I’m rubbing the bottom of the shock tower when the body rolls a bit.
Im running 245/35/20 on all 4. No issues in the back. Can I modify the plate to make work? Has anyone done this?
I think they will be to pushed pushed out if I add spacers.

Your tires are much bigger diameter than original set and that's why the rub. Did you compare the sizes?

So I found this website (http://www.rimsntires.com/specspro.jsp) where you get a clear comparison between wheels/tyres.
If I want to stick to my stock wheels then better to install 245/30/R20 8.5inch all around.
I found this info about stock wheels in my car user book (summer tires):
E350 BlueTEC: 245/45 R17 ET48 8 inch or 8.5 inch, rear and front (My stock wheels)
E350 4MATIC: 245/40 R18 ET48 8.5 inch, rear and front
nothing changed only 1mm in height from 652mm to 653mm
E350 4MATIC: 245/40 R18 ET48 8.5 inch front and 265/35 R18 ET54 9 inch rear (Mixed size tires)
Rear
E63 AMG: 255/40 R18 ET37 9 inch front and 285/35 R18 ET52 9.5 inch rear (Mixed size tires)
Front
Rear
E63 AMG (Performance Package): 255/35 R19 ET37 9 inch front and 285/30 R19 ET52 9.5 inch rear (Mixed size tires)
Front
Rear

The site above is generic calculator, who might be help in starting point, but tires are build with very loose tolerances and actuall tire can have dimension over 5% different than nominal.
That is why comparing rpm of actual tires is crucial.

I see, actually I have no issues with the current tyres 225/30/R20 8.5, no rubbing or anything else, but I would like to increase the tyre width to 245/30 R20
that's all.
that's all.
