Tire Pressure: Factory AMG package 225/50/16 Fuel filler door 32 front, 36 rear. Continuous speeds over 100 mph: Front 33, Rear 37 PSI. That is from the factory and I only add a lb or 2.
Snows? The Best are NOKIAN Hakka Q. Grip on snow and ice, quiet and very stable. Not great in the wet but it's the trade off for Ice. Also not as good in the dry, but they are snow tires.
I have some all season radials that are like slicks on the snow. Gotta have snows or I can just park it if it snows at all.
