Looking for advice on what PSI to run on my 2024 GLE 350.

I purchased a set of OEM 20” AMG twin 5-spoke wheels, as well as Bridgestone Blizzak DMV-2 275/50/20 size.

Wondering what PSI to run in the front and rear tires??

Getting the tires mounted as we speak, will update with pics.

Any advice would be greatly appreciated!

I've inflated my winter set (same wheel but with ipike tires) based on the gas cover numbers "normal load" target PSI of 31. I inflated cold on a upper 40f day to 34 psi to account for cold weather psi drop. We dont run the car fully loaded with passengers/cargo and on winter tires do not exceed 100mph.

I did 37 on my all-season ones and we'll probably do the same for winters. It gives some buffer for temp drops and some extra load.

Discount Tire recommended 35 psi for my 20" Nokians.

What is the "Normal" pressure indicated inside your fuel filler door? As this internal M-B graphic explains...

Hope that helps!

Somewhat related question... I'm about to go to the dealership to swap from all-season to winter tires too. However, these 20' wheels have different offset, while the tire size is the same. How easy is it to screw up the wheel placement on the dealer's side? I'm considering highlighting it when I bring the car in and maybe even placing stickers on rear wheels to make sure they stay in rear. There doesn't appear to be an easy way to check part number when the wheels are mounted.

We run the gas flap pressures for summer tires plus 2psi for our winters.

Ignore all the other stickers on the door post. They don't apply to recommended tire pressures.

stktyz, offset will vary from wheel to wheel from the OEM selection depending on the style. Front and Rear part numbers will be slightly different (ending 200 for the front 300 for the rear for example). The techs, hopefully, will be installing them accordingly. I wouldnt worry too much about it.
