I’m a little confused what tire pressure I should be using. The door jam recommends an eye-opening 40/46 while the fuel tank flap recommends 33/35 normal or 34/41 max. Which one is right? That 40/46 seems awfully high.



Fuel flap

Door jam

 

The label on fuel filler door is correct. My 2022 has the same labels. Mercedes-Benz: The Best or Nothing!

 

Fuel flap. If your tires get below that you'll have a lot of faults with the driving aids which cancan be fixed by airing back up to the min. The car rides best at the min and you don't need to worry about performance driving: As you've likely already noticed the car doesn't exactly encourage hooliganism even though it will move out if you absolutely insist.

 

I accidentally hit the spoiler button but can't figure out how to get rid of it.... *Facepalm*

 

Thanks, everyone.

I think I figured out why the door jam is so high. If you look at the fuel door there’s a note that says add 5 PSI for 100+ MPH. The door jam is the max fuel door value with that +5 added.

 

Never made that connection, thanks!
