wheel question on e420?!

I just have 16" x 7.5" ET37 with 205/55/16 tires and I can tell that the outside clearance is the issue. The problem is not the inner clearance, with my ET37. Even with my very modest +1 set-up, I had a little rub at the edge of the lower cladding at the front wheels when I had new Turanza LSH tires installed. Anyway, I think ET42 may be optimal.
If you don't have the lower plastic cladding, then you may be able to fit the 225 without rubbing even with ET35. Also, as you have read her I'm sure, there are guys running wider set-ups without rubbing. There seems to be some variability with fitting wider tires on different cars, just like experiences with lowering. I also think you should keep in mind that even though some get away with going bigger and you might also get away with it too, 17" x 7.5" ET42 with 225/45/17 tires may be the very best set-up for the W124.
