"New" S560; Already Damaged Tire

Turns out they were not tight enough on the center hubs, as these wheels are hubcentric. Literally took the thinnest layer of tape around the hub to tighten the fit and the vibration instantly went away is is now exactly like oem wheels were. I'm still blown away how strict the tolerances are in these cars.
I’ve found that 18” wheels on the W222’s, shod with cushy, non-run flat tires, improves ride quality substantially and give you a fighting chance when hitting more severe road conditions.
The big trade off is cosmetics. Bigger diameter wheels with shallower sidewalls look sexy, but ride quality takes a big hit and so does reliability. You have to decide which is more important to you. In my case, ride quality is paramount, so it’s 18’s for me and conventional tires. I carry a compact spare out of a W221 in my trunk, along with a jack & tool kit.
my understanding is that they should be ok to swap between 20 and 18 as long as the rolling diameter is the same.
that way I’ll get a feel for the way 18s ride, and eventually when my current 20 tires wear out I can replace them with whatever I like best
