Yes.
from Google: "The two-digit
number after the slash mark in a
tire size is the aspect ratio. For example, in a
size P215/65 R15
tire, the 65
means that the height is equal to 65% of the
tire's width. The bigger the aspect ratio, the bigger the
tire's sidewall
will be."
In my opinion, it is best to run a tire with the same circumference as what came from the factory. I have seen a few original spares in 240's that were 175/70, so I imagine that might have been the size that came stock. However, I don't ever remember seeing that skinny of tire being run on any of the W123's that I have owned (30+). I imagine a wider tire will have more rolling resistance, but it is probably minuscule. I don't think you will go wrong with running a 185 or 195/70 on your 240.
