40 psi
Any less and you risk wearing out the stiff sidewalls |

Not meaning to overtake this thread but I had my car in for a service the other day and the dealer advised and changed my tyre pressures to the bMW recomended for 19" wheels: 40 PSI front and 48 PSI rear. They said no difference in pressure for RFT or not RFT. I though 48 psi would be too bouncy and offer less grip in the wet but I have left it like that and the car actually feels better.

M-sport 17's in RE050A seemed best at 37/39 for road use and a couple of psi less on the track. Any more led to skatiness.

I'm running trying 36 front and rear at this moment. I use to run 40 front and rear and found it to be bouncy on rough road so dropped it slightly to get better traction on recent cruise. When I first picked up car, the dealer had the tires set at 45 which resulted in my traction control cutting in regular on slight bumps. Quote:
