Tire Pressures
I just picked up my 2018 GLS550 and it came with Conti tires. In the door jam it says pressure should be 38 front and, 50 rear
The gas cap has readings for heavier load but the numbers start at 32 front and 33 rear but the dealer put in 38 all around. They look fine but would like to know what pressure others do

Check the fuel door to see if there is an additional pressure sticker there. Most folks here believe that sticker is the most believable.

Run 36 all the way around . Thats what I do on my 2015 ML350 with 19 inch wheels 255/50-19. Just now replacing them with over 40,000 miles on original tires.

Went to dealer
Stopped by the dealer to get my manual. They told me 37 -38 all around and so I guess this is the range. I always went by the plate inside the door, but it seems to be riding well and fits with Isawelvis' view
Thanks for the feedback.

Door jam decal is for factory setting to prevent in-transit "flat-spotting" - fuel filler door is the "official" Mercedes settings - I have my techs set at 38 psi all around - after driving one week - go up or down 2 psi if you want firmer or softer - drive one week - and make your final PSI decision
