Officially recommended tire pressure from Mercedes?
I have a European spec '08 S500 w/ AMG Sport Package which includes a 19" staggered setup. The tire sizes are 255/40R19 front and 275/40R19 rear.
Strangely I don't have a placard on the door pillar showing the recommended tire pressures, but there is one on the fuel cap and it recommends 29psi front and 32psi rear for the lightest load under 130mph/210kph.
But the placard doesn't say what tire size the recommendation is intended for. Neither does it say Sport package nor AMG wheels/tires, and I doubt Mercedes makes a different sticker just for the AMG Sport Package, and if they did, it would say on the sticker which trim the recommended tire pressure applied to. And I'm thinking maybe the fuel cap info is for S550s with 18". Or maybe they are the same. I'm confused.
Does anyone know or have a picture of the officially recommended tire pressure for the 19" AMG wheels? BTW I'm running on Hankook Ventus V12 Evo.

@autoque, tire pressure is not dependent on the tire size. let me put it this way what ever the tire size pressure per square inch (PSI) has nothing to do with the diameter of the tire, it has more to do with the tire profile, 35, 40, 45, 55 series etc. I strongly suggest all those who are not familiar with facts on tires go google this subject matter, tire and breaks are the most important component of a car in terms of safety.

Thanks for all the replies. I have a picture of the placard on the fuel cap door.
I really wonder why they have such conflicting info on it. I do think 29/32 is low but it's what the placard says...
See how it says +3 psi for 20" tires?

whether it is a 13" to a 22" wheel diameter, tire pressure is measured in lbs/psi for a 35 to 50 series tire 34 psi is enough, as you drive for a few miles the tire pressure increases and if you put 38lbs/psi, good luck and hope it does not blow up and cause an accident. unless your using nitrogen gas for your air. Tire/ Air running under heat pressure increases lbs/psi due to temperature and friction, will cause tire to expand and can cause serious accident or a blow out.
BTW which factory recommends the 38 lbs/psi and what tire brand, size are you using?

It also says to allow up to +4 for warm tire pressure, so thats about 42 psi. After warming up, mine usually go at about 40 psi

I am using the factory Continentals I believe and the 38psi is the correct pressure. When I first bought the car they were set to this pressure. I also checked the info at the door and for my tires and wheels that is the pressure it recommends.
It also says to allow up to +4 for warm tire pressure, so thats about 42 psi. After warming up, mine usually go at about 40 psi

I also posted about tire problems on my 2007 S550. And one factor is the correct tire pressure. My placard on the fuel filler cover says 29-32 range and same info on the driver door pillar. For the Michelin Pilot Sport A/S 255/45-18, I found it too soft. I have upped the pressure to 35 psi and no improvement. Tires are wearing out on the edges, uniformly. Tires gone after just 13k miles. The conclusion was the tire sidewall flexes during turning. I changed tires to Continental extreme contact DWS 06. Tires are rated for 51 psi max pressure. By trial and error, I found that 37 psi is the least pressure to reduce my issue on tire improper wear. I mentioned this situation because my tire pressure info on the car appears to be wrong? too low. or MB revised it after my car built date? Anyway I am glad to know that the pressure I put on the tires are not too high or out of line. Now I can feel confident to up it to 38 psi which will give me slightly better margin for minimizing tire edges wear.
Thanks for the info.

Sorry, I do not want to be irrelevant to the topic but I found it a useful confirmation to one of my tire issue concerns.

Tyre pressure
I understand what you're talking about but in my country cyprus which the asphalt temperature probably is around 60 or more celsius i use 40 psi no problem at all if i use less i will destroy the tyres

If running the correct tire pressure is destroying your tires, then you have some major suspension or alignment issues that you need to get resolved ASAP.

What if the gas door specifies 32 front/33 rear and the door pillar specifies 36 front/39 rear cold? The manual says to refer to the door pillar. Car is a standard 2017 S550 with pierelli run flats. Conflicted about what I should use.
