tire pressure for the 19 inch non-amg wheel

I have been using the sticker on the inside door post for my tire pressure. 36 front/42 rear

I just noticed my sticker is a partial sticker over a sticker and it says full load in very small print for those pressures.


I just put gas in the car and there is another sticker indicating 35 front & 35 rear.

What pressures are you guys using?

The inside door post shows the pressure to use when the vehicle is operated with "maximum load". The sticker inside the gas cap gives both the "normal load" (35/35) and the "maximum load" (36/42) pressures.
I use the 35/35 normal load pressure.

I have the AMG wheels so this may not apply.

Don't forget to read the note on the bottom of the fuel filler door. You can drop the tire pressure by 4 psi for speeds less than 100 mph.

You can drop it even further for less than a max load in the car. I run 32 psi cold for around town.

For my trips up to the Smokies, with my wife and a full trunk, I run the max pressure on the filler door, 36/42 psi.

Hey DAYTONA FLYER...suggest you don't let your wife read your POST (chuckle-chuckle).
