Spent a while with the door placard, sorting out which pressure for what tyre and didn't fancy trying to decipher it every week, so I made up a little chart for my 535d M Sport on factory fitted 18" wheels, which I'll attach to the door post with wide clear tape.

I couldn't attach the 'xls' page, so had to convert to pdf, but you'll get the idea. Anyone who's interested can reformat it in 'excel' and fine-tune to fit their particular set-up.

I've got the factory fitted 18' as well. Only looked at the profile of one of the tyres and assumed all 4 were of the same profile. According to your chart, the front and rear have different profiles. Will have to check that when I wake up.

i run 2.0/2.3 (front/rear) on my 245/45/R18 (run-flat tire)

i accidentally over-inflated them to 2.3/2.5 for a few days and the ride became a lot more bumpier.
