What does it say on the label on the fuel flap or drivers door pillar?

There after market wheels not originals

Tyre pressures are a function of axle weight so wheel design and different tyre size doesn't greatly impact the MB recommendations. Run them at the recommended values and adjust to suit ride quality and wear.

So what tyre pressure shall i run them at please?

On the subject of tyre pressures, I did my (admittedly only) monthly tyre pressure check yesterday, two weeks after a major service by Mercedes. All four tyres were down by 5 psi on the recommended values.

One of the service items is to check tyre pressures. Either they’ve all lost the same amount in two weeks, or Mercedes reset them incorrectly. The former would be extremely unlikely. BTW, I checked them with two different devices.

Also, I noted on the service report under “spare” that “kit - OK”. Since when was a spare wheel (yes, I have a real one) a kit? In previous years they’ve noted that the spare tyre had no wear and what the pressure was. I suspect they didn’t bother looking this year. It’s a good thing I check it from time to time.

Doesn’t fill me with lots of confidence that the plethora of other service actions were carried out fully.

What normally do you run yours at? Theyve more than likey put them back to the recommended values.
As if they were losing air they wouldn't be all sitting at -5psi

As I said in post #4 run them at the recommended pressures shown on the fuel flap or door pillar label. They are also likely given in the owners handbook.

I run mine at 36 psi all round, which is the figure given for my wheels behind the petrol flap. (But well below the figures given for a fully loaded car.)
