19" tyre pressures. Suggestions?

Soul_Glo · 06-20-2018, 11:35 PM

What are yours set to?

I tried 35 rear and 34 front and for a while it felt okay but don't think it has helped fuel economy much.

Thanks

I run 38psi all round on my 19s

After a bit of reading on these forums a while back I came to the conclusion that the most widely accepted pressures were;

36 PSI fronts
38 PSI rears

That's what I run now.

Is that fine for x-drive too?

Unless you're running different dimensioned wheels and tyres from stock (makes no odds if the tyres are run flat or not) , just use those stated on the plate on the drivers door shut.

2.4 b - front = 34psi 225x40x19
2.5 b - rear = 36psi 255x35x19

As the door card

It should be on the plate on your car. Mine is 32psi front and 35 psi rear, which is fine.

I think there is a difference on the door card info between saloon (F30) & tourer (F31)

I used to run the lower door card figures on mine 35 PSI front & 38 PSI rear, until speaking with you (Dr Forinor) and now run 36 PSI front, which I'm finding better.
