20" staggered 2014 e350 4matic. Can't find the answer
Guys I know it's out there and I have been searching, reading everything on the forums but I can't seem to find the right answer. I want to run 20" staggered on my 2014 e350 4matic. What is the rim/tire size without any modifications that may work? Thank you in advance.

I am not sure where the circumference difference would set off the speed sensor fault, but on a 4Matic it would not take much.

Good luck to the OP.
I've looked into this for my own E550 4Matic, and found that a 245/35-19 and 285/30-19 pair only has a 0.08% difference. Better yet, this set only has a tiny difference in diameter compared to my stock square 245/40-18 wheels (0.06%). I have no idea if these hypothetical 19" wheels will actually fit without rubbing.
Moving up the wheel diameter, a 235/35-20 and 275/30-20 pair has an even smaller diameter difference of 0.07%. The problem here is that this set has an overall diameter that is about 3% larger than a 245/40-18 set. Playing around with the numbers, it is clear that once one gets to 20" rims, one will need to go below a 30-section aspect ratio tire to get a comparable overall wheel diameter – something like a 245/30-20 + 295/25-20 is a more reasonable 0.35% larger overall, while still maintaining a 0.08% front-rear diameter difference. I was curious enough to find out that Tire Rack only offers one model of this size pair. In comparison, the 19" staggered set has 12 choices.
I will leave the reader to judge for themselves if a W212 looks good with giant 20" wheels with skinny rubber band tires (and visually tiny brake rotors).

I haven't had a speed sensor fault message with this setup for over 10k miles yet. Some rubbing in the rear, but not often and it doesn't rub hard enough to leave rubber on the fenders. The front rubs on hard bumps, and it rubs against the front bumper bracket (where the bumper mates to the fender), but if you shave it down a tiny bit, the rubbing goes away. Springs with a higher spring rate would probably completely eliminate rubbing. It goes without saying, you can't drive too fast while riding with these wheel specs.
285/30/19 Rear
255/35/19 Front
Wheels are:
19 x 9 Front
19 x 9.5 Rear
They are OEM E63s Wheels.. And because I was being lazy the day got them, I had the SA look up the stock tire setup for a 2014 E63s, which is 4matic, so I didn't have to do the research myself. Mercedes system calls for a staggered setup.
As long as the difference isn't crazy, you should be fine. Technology changes. 4matics are better suited to handle these differences than they were when they first came out. That fact is proven further by the newest models that come from the factory staggered..
Keep in mind, the year of your car might be a factor. If you have a newer 4matic, you should be fine. If you have an older one, I wouldn't risk it..

The circumference and revs per mile is what the computer sees.
The E63s is an amazing machine, but the 4 WD system is not a typical 4Matic system for the US market. 4Matic is a 45:55 torque split and the E63 is 33:67.
I agree that since 2012 the 4Matic system is much improved, however just be careful when comparing the normal 4Matic to the E63, which also has a LSD.
As long as the difference between front and rear is very close then there should not be an issue. I would also stick with 19" as you have.
