OEM Tires Pressures -2012 E350 Wagon with 18-inch Wheels

I am upgrading my 2012 E350 4Matic Sport Wagon from the stock 17-inch to 18-inch OEM Mercedes wheels (18x8.5 all around) with the recommended 245/40-18 tires (all around).

Can someone with a 2011 or 2012 Wagon with the R08 wheel package option (18-inch wheels) please post a photo of the inside of the fuel fill cap so I can see the normal and max load tires pressures for the wagon with the 18-inch wheel option?

It continues to surprise me that Mercedes doesn't post the recommended tire pressures for all the different available wheel/tire sizes in the door jam or the owner's manual. They also need to post recommended winter tire pressures. What if an owner with 18-inch wheels wants to install 17-inch winter wheels/tires? As I've noted in the past, BMW posts all this info in their owner's manuals and it's very handy. Mercedes should really do the same.

Have you tried calling your local dealership's service or parts department and asking one of them as to the recommended pressure?

I know this is an old (2 yrs old) thread.

BUT tire pressure is tire pressure. it does not matter if you have 15" wheels with a 44" tall tire or a 22" wheel with a 24" tall tire. 35 psi is 35 psi. now the volume of air in the 44" tire will be greater than in the 24" tall tire.

I set all my tires when I do services at my dealer to 35 psi front and rear for cars. if its a SUV than I set them at 36 frt and 37/38 rear. tire size and wheel size makes no difference.

IMO for winter tires run them a tad lower to give yourself a wider foot print.
