Pressure for 20" tyres

Hi
Just curious what pressure people generally use for 20" run flats? As i recall mine are currently set at 2.3 (fronts) and 2.4 (rears).

You could either follow the recommendation on iDrive or your tyre size of refer to the sticker on driver side door pillar. I usually go by the door pillar and iDrive is generally happy with it.

I recommend just doing 2.4 bar all around or what you have right now is fine too. The bmw recommended is gonna be like 2.6 front and 2.9 rear but you'll find your tires feeling like rocks with those pressures xD

I go with 1 or 2 PSI lower than iDrive recommendation which is 39 PSI (almost 2.7 bar) all around when cold. 540i xDrive
