tire pressure

[feelstranger]

Hey, 
I have looked in all the usual places for the tire pressure sticker on my car to no avail (gas door, under hood, door jambs..)
The manual says look in gas door flap as does Bentley...
So, what are the recommended tire pressures for Avants?
FWIW, the PO put 225's on the stock BBS and I assume there should be a difference for tire size.
suggestions for this?
Thanks
Nat
