When it comes time for new tires, I am nit sure if I will put run flats on or not. I have been told they weigh more, wear faster and are more expensive. Even if I had run flats on it, I think I would still have the doughnut in it because ...well thats how I was raised. It would be nice to have more trunk room but I dont think I can bring myself to ditch the doughnut.

Decisions...decisions.

That’s a great idea. There’s a wheel well for the spare, just no spare and no jack nor tire wrench.

MB offers a jacking toolkit for the 2021 C300 as an accessory:

If the storage in the trunk will fit a full size spare I would suggest considering finding a matching rim and going the full size spare route.

My wife had a flat in her subaru last week and being able to put on the full size spare then go to the tire store when it's convenient was super nice.

I guess it may vary on the car. I have a wheel well in the trunk but it wont fit an inflated spare the same diameter of the actual drive wheels. If I had to guess, it probably will accommodate one of those collapsible spares. My spare is sitting in a carry bag supplied by the vendor. It takes up a lot of room but I'm old school and just cant drive without a spare even if I had run flats.

Odd thing is, we have a '21 GLC and it has run flats that it came with but also has a spare (full diameter) that fits in the wheel well under the deck in the back.
