New 2021 GLC 63s Coupe owner - tire pressures

Hello,

Traded in a 2020 BMW X3M Comp for GLC 63s AMG today. Any recommendations for tire pressure? Car came in 21 inch cross forged black rims and the tires are Pirelli's. Dealerships always seem to overinflate tires. I love the car's suspension, much more comfortable than the X3 M. Any recommendations? Thank you!

I run the low side of what it says in the gas filler compartment and drop that by 5 when doing dragy runs.

I use the “normal” pressures on the gas filler door. The B-pillar sticker seems to match the “loaded” pressures found on the gas filler door. My manual says to reference the sticker on the gas filler door.

I inflate my tires to 32 psi to maintai ride comfort as our roads in Montreal are in terrible shape.
Here is my gas filler door sticker.

My 63 SUV has 42s up front and 39s in the back, from dealer.
Not sure why i have 2 sets of stickers with different recommended tire pressures.

I run 40 psi cold on all 4 tires, stock was at 36F 31R and I noticed that tire temps are a lot lower with higher psi.

@Ftpohyeah
Do you have a sticker on the inside of the fuel filler lid? It looks like the sticker with the 42/41 is for when the vehicle is heavily loaded and the 38/42 for normal load to me. Probably best to confirm with the dealer, but in my experience the dealer typically puts extra air and I think it's to avoid a low air pressure warning message between visits.

@Regis I have the exact same sticker as @tedboss1 first car ive owned with 3 different tire pressure stickers. also, front 33 with rear 31 seems low to me.
Me, my wife and my 2 yo are just about 400 lbs so maybe ill do 35/35 but the ride is pretty good with 40/37 altho the bumps are intense.

I use the sticker on the fuel filler door, and I think for normal load is 32/32 and heavy 35/38 if I remember correctly. I run mine at the normal load as I find the heavy load pressures to be a bit harsh for my everyday driving.
