I have never seen an all wheel drive SUV with different size tires on the front and back. The tire sizes you state are on the ml have different diameters/radius' not alot of difference but a differance none the less
Best way to check what tires are recommended is to look at the tire/rim information in the door jam, If you bought the vehicle used maybe a previous owner threw on a mis-matched set of tires just to sell it.
255/50/19= 29.04 in. diameter
285/45/19= 29.10 in. diameter
different tire manufacturers sizes may very
correction,
265/50/19= 29.43 in diameter
285/45/19= 29.10 in. diameter
and that is even worse then numbers above, and in my opinion way out of spec for an AWD vehicle

Reason: math incorrect
Unfortunately Tire rotation is not possible to make,because different size tires.
Front 265/50/19 Rear 285/45/19.Indicator lights ESP.
The tire sizes you say you have on your car are not the recommended size from the MB web site you linked to, unless it was a typo.
And you are correct, if I have never seen it, it doesn't mean it isn't possible
and for that matter, don't believe everything you read either.
I would be looking at tire replacement before I started rebuilding the front end.
If the front end is wore out at 100K maybe the car was used for baja rally's,
I think MB builds cars that last longer than 100K under normal driving conditions.
