2022 C300 4-Matic sedan (206.047). Replacing original Bridgestone RF tires with Pirelli P7 conventional tires. I would like to make up a donut spare tire given no more run flats. Anyone done this? If so, what rim and tire will work? Do I need different lugs? Is there a jack kit available that works with this car? Sources for these items? I know there is no spare tire well on this car (battery is there) but a donut wouldn't take up too much space and I plan on simply securing it on the floor of the trunk. Thanks.
