Those that have removed RFTs

What tyre pressure are you using for

18's?

19's?

Been experimenting a bit with mine the last few weeks.

I had Conti 5P's on my 335i, and ran 36 front and 38 rear after much experimentation. That was on 19 inch Style 230's.

On my 18" I tend to run few PSI higher then stock as using non RFT. So if 35 I set to 38 etc.

Same tyre, same wheel, same car and almost identical pressures to what I've got. I'm running 35 front and 38 rear all seems fine

The joys of programming autoclaves, BAR to PSI is second nature

How come you guys all quote in PSI?
My car only has the bar figures in the door.

When I removed my RFT's I stuck with the same pressures.
Only 17", but I stick @ 2.9 Rear and 2.4 front.

Same as the door plate but I can't cope with BAR so I've got the PSI equivalent written on my pressure guage
