Winter tyres are often specced with a different size (width and/or diameter and/or profile) to 'std.', however, there will sometimes be a lower recommended max speed if winter tyres fitted (can be set in the speed-limiter). The narrow tyres are specced for 'better cutting into snow and/or suspension/steering clearance for the fitting of chains.
I'd also be wary that changing the size to a non-standard one might (but might not) be an issue for some ins. companies. There is, no doubt, a specific reason that MB specify a narrower rear tyre (and possibly wheel) on the rear of the estate and if it was mine, I'd simply stick with the specified tyre sizes.

and the roads have seen happier days. I first noticed the tyre size difference recently, as I am planning to change tyres around Summer time. My first Mercedes was a C-Class CDi Estate with all 4 wheels the same. When I moved on to the E-Class CDi AMG Sport saloon, I did not realise the wheel setup was different initially.
