Just ordered these for my 3.0 auto. Having sent half an hour searching here still mr confuses...manual pressures states

225/40 R18 - 33 PSI
255/35 R18 - 36 PSI

Thoughts?
 
Well if you've searched on here you will have seen that there is no definitive answer. Some run stock pressures - working on the principle that the car hasn't changed. Others run slightly higher pressures - working on the principle that the sidewalls are not as stiff as runflats. And then you could check the Vredestein website that shows much higher pressures. So try stock and see how they feel. :driving:

Sounds good advice! :thumbsup:
 
Generally there will be a range of acceptable pressures. Bear in mind that pressures will change as you cover off the miles....

I run 32F and 36R on my non run flats with no issues.

Experimenting 3/4psi either way won't do any harm :) If you find the car behaves more with higher/lower psi, stick with it. Bear in mind though that if you're too high or low it can affect MPG and tyre wear.

I ran 32 front and 34 rear 235/35/19 and 265/39/19 respectively on my Vreds over the weekend without issue, as others have suggested play around a bit and see what works for you.
 
I asked the fitter for 32F, 34R. Just checked, 29 all round :roll:

To be honest that felt fine, but I've changed to 32 all round to see the difference
