New (to me) S560




I also realized that your new tire size is 255/40R20. Since yours is not AMG wheel, is it ok to use 255 to replace 245 width? Is your new set having same size rear and front? If so, are they fitting well?
It is the first S class I have, I don't have too much knowledge. I had C and E classes before S class. a lot of information I can find for C and E class from the website, not too much about S class. I think I found the right place to know everyone.

Secondly, that’s not an AMG package.
Thirdly, I have an S560, not an S450.
So, all that being said, the fitment from a W223 to a W222 is seamless. I actually like the fact that the wheels and tires are squared. I can now rotate. There is one thing I may do, and that is to put a 10 or 12 mm spacer on the backs. The fronts fit perfectly, the backs sit a little bit more inboard, which is perfectly normal for OEM. If you have a rear wheel drive, you may want to consider going down to a 19 or 18 inch wheel. That is what I do on all of my vehicles. I always go down at least one size if not two. Again, gorgeous car! Hope I was able to help.

Will smaller rims help the handling in the snow? I thought the narrower rims could help in the snow. I tried to understand better to choose the right tires.
Thanks a lot

Ride quality wise, no doubt they are the best and that’s also reported by TireRack pro test results.
As for their performance results, see the TireRack results below yet against one of the 2 best options in the industry.

Nokian is a Swedish company I believe. You can buy them at Discount tire. A little ironic that they own Tire Rack but you can’t get them there.
Tire pressures are key, if you want your S-Class to ride the way it's intended (see instructional graphic below). Despite this clear guidance from Mercedes-Benz, my dealership routinely OVER-inflates my tires during service, which I notice immediately when I start driving away... "Why does my car ride like a buckboard?" So I pull over and usually need to let out between 4-8psi, to get the pressure back where it should be. I assume the tech is consulting the wrong label (door jamb), rather than the label on the fuel filler door.
