18s with AMG Sport Package




To take this a step further—and I’m no expert on tire construction—I would venture a guess that the manufacturers make lower profile tire sidewalls stiffer, just to compensate for the lack of material to absorb road imperfections.
The bottom line is that a tire with a deeper sidewall will offer a softer ride than the same tire with a more shallow sidewall. Which type of ride one prefers is simple, personal preference.

I also realized the significance of the lug bolts requiring 110 ft lbs. A person would need a pretty stout wrench to produce enough torque to remove a wheel from our cars. Thus, the decision by Mercedes not to provide a jack, spare tire and tools comes a little more into focus. Moreover the 20" wheel and tire are pretty darn heavy, so again, many people might have real difficulty changing a flat even if they had the jack, spare and tools on hand. Obviously, most of us would just call AAA or some service to come out and do it, but then you'd be relying their guy and his equipment, so why carry it around in your car?
I still like the idea of the creamy smooth ride on 18s and non-run flats, so looks like the closest thing will be 19s and run-flats.
