E Class Coupe wheel/tyre advice please

[Telxxl]

Guys I have a W207 E350 Coupe Sport. I want to change the wheels to either 19" or even 20".

I would greatly appreciate any feedback on wheel offsets and tyre sizes.

I also want to know if anyone has tried 20" wheels and if the ride is unacceptably harsh?

Any feedback would be greatly appreciated.

Guys just an update, 35mm offset on front works OK but not on the rear. I would suggest 40mm or even 45mm on the rear. This is with 19" wheels.
