What tyre pressure are you using for

18's?

19's?

Been experimenting a bit with mine the last few weeks.

Phil325i · 03-01-2013, 11:33 AM

18s and stayed with original manufacturer's settings.

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.

Dragon88 · 03-01-2013, 04:34 PM

Same as door jam pressures

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

Sparky68 · 03-01-2013, 04:57 PM

I was running 30 and 30 and thought that was high! No wonder my mpg was shit, well that and my right foots lack of ability to not plant at every opportunity!

18"
front 2.35 bar
rear 2.55 bar

not sure how much that is in psi, i went .05 bar higher than reccomended and find it spot on

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

raf555 · 03-01-2013, 05:50 PM

235/35/19 fronts - 38psi
265/30/19 rears - 40 psi
Mv4 with non Rft

xPETEZx · 03-01-2013, 06:01 PM

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.

Sparky68 · 03-01-2013, 06:02 PM

PSI Oldshool , British Imperial measurement.

IanS100 · 03-02-2013, 07:41 AM

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