Will these wheels fit
Front: 20x9 ET+40
Rear: 20x10.5 ET+40
And if you think they may fit, what size tyres would you recommend to avoid rubbing?
Thanks.

Front: 20x9.5 ET45 with 265/30/20 Michelin Pilot Sport
Rear: 20x9.5 ET40 (same as front but with 5mm spacer) with same 265/30/20 Michelin Pilot Sport
Zero rubbing for me, I also have AirMatic, lowered about 25mm from stock
I would probably suggest that you go with 255/30 for front and 275/30 for rear to avoid rubbing,
This is how much they stick out with the offsets listed above, your rear will stick out a further 0.5" (12mm) than my rear, your fronts should be about the same as mine

Also, I was going from an OEM Mercedes wheel to another OEM Mercedes wheel, so the back pad thickness was relatively the same. If you're going from OEM to aftermarket, I would measure the backpad thickness as it might not be same as OEM. By back-pad thickness I mean the distance from the lug seat to the back surface of the wheel. Going OE to OE they are relatively the same, but aftermarket can be any thickness.

Mercedes uses same thickness back pads on all wheels so they only have to stock one lug bolt size. If you add any spacer wider than say 3mm, you'll need new, longer bolts
