New tires is a good opportunity to calibrate the speedometer/odometer on
your car. If you can drive a precisely known distance (such as
speedometer calibration markers on the freeway) you can calculate a
factor by which your current odometer is off, and then use this factor
to determine your correct tire diameter relative to the one you have
now. Width probably doesn't matter that much; anything from 175-195 is
fine. Skinny *might* improve fuel economy slightly, and *wider* might
give you a slightly better ride, and handling- but differences in tire
design and composition will probably matter more.

What size do I want? Something in the back of my mind says 175/70R14 would
be stock but I can't remember.
Tire rack surprisingly gives zero suggestions...
I think it was 175R14 for your 240D and 185R14 for my 300SD. Aspect ratio on
those tires was something like 83, certainly NOT 70.
I wish I could find revolutions per mile data on this:
