Useless spare tire?

Or are you concerned that due to the offset the front wheel won't fit on the rear?
This should be no problem: the front is 8.5" wide and the rear is 9.5" wide.
Both rims have a 43 mm offset
That would mean that a front wheel mounted on the rear has 1/2" more inner clearance and sticks out 1/2" less from the wheel arch, so it won't look too great but should be much safer than the donut wheel.

Hmmm, I would think that using a 255 spare tire on the rear (instead of the 275 which is on the rear) is way much safer than the donut wheeel.

The same could be said for running the narrower front wheel & tire on the *** end of an S600... should be fine as long as the tire is in good condition, inflated properly, and not driven at high speeds because now you've got an oddball combination of tire and wheel sizes with not entirely predictable handling characteristics. Not AS bad as the donut, but one would still be wise to limit one's speed somewhat.
So, personally I'm not seeing the advantage. You wouldn't need to carry extra studs, though I don't know if the spare tire cover in the trunk (the trunk floor) will still fir properly. Haven't tried that. And for whatever reason, I don't recall ever seeing a donut spare that needed air in it. I can't say the same for full sized spares. My truck has a full sized spare slung underneath, and I have to check it a couple times a year and fill it from time to time. The donut in the S600 hasn't needed air in the two years I've owned it. Not a huge deal, just a little additional check during the maintenance cycle.
But, to each their own. Different people have different priorities, so go with whatever makes you happy. The blown front on my car was the first tire I've had to change on the side of the road in the past 8 or 10 years, so it's not a big priority for me -- now that I have the proper studs to mount the silly thing, of course.

That's why I am considering replacing the donut with a full sized (255) spare. I am 100% sure that as soon as I have a full sized spare I won't be needing it anymore though :-)

Thank you, thank you, thank you. Mercedes calls that part number a "spare parts box". It's a package with the five bolts. All over Ebay used for $35-$40... or I can order it brand new from my favorite M-B dealer for $15.99.

Depends on the weather
The strangest thing is I can drive thousands of miles from MD to FL and everywhere else and back with no tire issues but yet when I am within a mile or two of my house, it's the only time I have had a flat tire.

I can't speak to your side of the country, but around my neck of the woods... highways typically don't have monster tire-eating potholes. Local surface roads do, in abundance. So if you can dodge them on your way to and from the on-ramp, then you're golden.

Indeed once you get aftermarket wheels, almost never will the lug bolts work with the spare in the car. If one cares to, one must make sure before you get a flat that you have lug bolts that will work. I don't bother because I have AAA and would just go to the nearest tire shop and get a new tire. Naturally, they probably wouldn't have one on hand and would have to order one, and of course the wait for Triple A would be hours. Usually when I ever called Triple A and made cure they know I needed a TOW they invariably send a fool with a battery checking tool, who wastes a long time to arrive then wastes more time playing with the battery, then orders the tow I told them hours ago I'd needed. I've quit Triple before due to this kind of service. But, re-joined just because I want to be able to get a tow when needed.

It's only during the winter, which I typically don't drive it that much anyway but the highways can get rough from the weather, not to mention it's always new construction taking place somewhere along I-95.

I ordered a set of those spare lugs Dale wrote about today. As you all know, I have suffered three front tire blow outs from pot holes. I wrote about them in another thread. Michelin PS3s. I decided, the real problem is insufficient air pressure combined with the low low profile. I don't want to lose the nice ride nor the handling in turns which is fabulous for a big heavy car, so I am keeping the low profile staggered 19s. But I am pumping each tire up to 39 pounds cold which means they run about 42 pounds of pressure at road speeds. I think the extra 10 pounds of air will provide a better cushion when I decide to explore the pot hole canyons again. I will keep you posted.

And if you put some weigh in the trunk, the lids are now supported by the spare tire

Follow up to this story:
BEST investment I ever made. While on a road trip my rear tire caught a nail. I wasn't able to find a tire shop that could fix it (very long story).
So I put my new "full size" (front wheel) spare on the back and drove home w/o any issues (even though the rears were now slightly mismatched)
My local tire shop then patched the tire for $20
Thanks again for the tip!

I just traded in my W221 for a Range Rover Velar. If anyone (local) is interested in my spare wheel (see above), PM me
It's a pristine new rim with a brand new Michelin AS/3 tire (both front wheel fitment)

FYI …
… note that for the “donut” spare wheel, on Mercedes, the air valve for this wheel is an off standard part that you won’t be able to find anywhere except from a Mercedes dealer. I carry a spare.
