what is the correct tyre pressure for everyday use?

[flimper]

I've just bought my Z4M and checked the tyre pressures today. The fronts are running at 25 psi and the rears 27.5 psi. This sounds very low compared to the recommended pressures but I must say that it feels absolutely fine. On my old 330ci when I ran it on the recommended pressures (mid 30s) it never felt like it handled well until I dropped the pressures...

I've been doing some geometry set up work with a specialist on mine and am now down (Falkens - non RFT's ) to 30 rear 28 front and it feels the best since I had the car. Been dropping it in 2 PSI increments.

OEM of 36 on the rears felt all wrong on the Falkens

Just had the rears replaced and it's handling like a pig :evil: Checked the pressures and it's 32.5 front and 34 rear. Going to lower them and hope for some improvement.

30 front and 32 rear now and still not happy with the handling. Gonna drop it again and hope it sorts it :evil:

I've got it down to 29 front and 31 rear and it feels a lot better than before, not perfect though
