run flat tire pressure

Can anyone help me with the recommended tire pressures, my handbook implies there should be instructions on the edge of the driver door but there's nothing there.

I have a 540i xDrive M Sport with the 245/35R20 95Y on the front and 275/30R20 97Y on the rear.

The idrive is telling me the front left one is low at 37 but the others are green at 38. I'm not sure what to inflate them to. Thanks

Have you checked the passenger door side (in case they've mistakenly put the sticker there)?

I'll take a picture of mine tomorrow and post it if you haven't got it.

Idrive tells you both current and recommended pressure for each tyre.
Just make sure you select the correct wheel/tyre sizes you are running.

Thanks guys, the iDrive is set to "other" under tire type as the ones I have don't appear to be an option. I guess I'll set them to 36/44 cold and perform a reset on the iDrive.

Ah yeah you're right. Well I set it to those tires and it recommended 38psi for all 4. Although that's quite different to the sticker suggesting 36/44. Strange

Here's my sticker as promised. I suggest you go for 35/38 if you only have 2-3 people.

Yeah the 36/44 is the pressure of you have a full load of people and cargo with the 17/18/19" tires.

Interesting. Must admit I've only looked at idrive rather than that sticker.
Will have to have a look as I might be running higher pressures than necessary , ( will idrive flag that if I lower a bit? mmmm)

I don't think so. My understanding is that once you reset the system with lower pressure, it'll simply monitor the new circumstances.

I'm running the 19" 664m wheels and my iDrive was moaning yesterday that the front pressure was too low. It recommended I set them at 33/34.
