Good Day to All .........well, I've been reading almost all wheels related threads on this wonderful forum and I'm now a bit confused on the so many different opinions on Wheels/Tires specs for our cars, hence I'm in need of your kind assistance on this one dear fellow members.

I have a 2014 E350 4Matic Luxury model lowered on Vogtland springs about 1.6" front and rear.

maybe a mistake that is too late to revert, but I recently went ahead and ordered custom forged wheels:
19x9ET32 front
19x9.5ET42 rear

I'm now worried that I ordered the wrong wheel specs for my car, also what is the best Tire specs combo to go with the above wheels if they'll fit ?

can anyone with knowhow in this area help me please ?

Those wheels should fit... not sure about the tire sizes though. I think 235/40 or 45 up front and up to 275/35 rear is what some guys are running on 19" wheels... but don't take my word for it.

You really need to pay attention to the circumference from front to back with your 4Matic or risk burning up the transfer case. I am going to mount some 19" E63 wheels on my 550, but the offsets are more acceptable for larger tires
They are 38ET up front and 52ET out back. I will mount the tires in the following chart and you can see they are almost identical in terms of circumference and revs/mile. The 52ET in the rear allows for the 285 tire to fit whereas your 42ET pokes the wheel out to far to mount this size tire without rubbing. You will need to play around with tire sizes to make sure your staggered setup does not cause issues with your 4Matic

Thank you for your assistance Gentlemen...my research indicates 235/35/19 front and 275/30/19 rear is the perfect combo in terms of Circumference.

i now hope this wheel/tire combo will fit without rubbing.
