What tire pressures is everyone here running on their S63?? I'm confused because the sticker has them all over the place. I have the 20" AMG wheels. Normally don't carry a heavy load and just one passenger, me. Sticker says 35F/33R... but the recommended pressures range anywhere from there up to 51/49. I've also heard of a lot of people running 38 PSI all around. I'm not driving on the autobahn so it's rare that I would approach anything over 130 mph. I just got brand new Michelin Pilot Sport All Season 4's.. and discount tire inflated them to 51/49! lol

Thanks

Solo driver 80% of the time, not loaded with cargo, 18 mile commute/40 min drive, normal speeds. The other 20%, wife and newborn in the back, trunk filled with light luggage, 200 mile round trip to weekend home, 100mph sustained. 36 psi front 34 rear, no issues thus far even with the horrendous NYC roads.
