Why Tire Pressure Recs Differ
My 2017 GLE 43 has two spots on the car where recommended tire pressures are posted.
The on at the drivers door says cold psi should be 44 in the front & 47 in the rear tires.
But the one inside the gas filler area says the recommended psi is 31 for the front & rear.
That's quite a difference.

I pushed the button near the mirror in the car to call customer service.
They said the sticker you see when you open the driver's door is the tire manufactures recommendation.
The sticker at the fuel-filler door is the one Mercedes recommends (31 front & rear).
You'd think with that big of a difference,Mercedes would have made it clearer.
BTW
They said go by the tire manufacturer's psi rec for the spare.
Go figure.

The TPI alert can come on at any pressure. You set that alert yourself. It was originally set at the factory. After you set it at the pressure that's in your tires, if the pressure drops a few pounds it alerts you. I put 37 pounds in all around and reset the alert from that setting.

Thanks for the tip. I'll check into that...

I kind of split the difference, and I'm running 40PSI as my base. The higher that pressure goes, the stiffer the ride is going to get...

Well.. yes ....and yes
yes - the driver's door jamb are pressure to be set at the factory - which are higher - to help prevent flat spotting during transport.
Yes - fuel filler door are the correct MB consumer suggested pressures
Yes - your TPMS system can be reset to set current pressure as baseline for the alert system.
Yes - the higher the pressure _ the "harder the feel - and also in general terms can extend tire life a bit.
Best practice - set at fuel filler door pressure - and 2 weeks take all tires "up 2psi" - drive that for a week/10-days - and then go up another 2lbs - until you have "dialed in your sweetspot"
