Default 18 inch PFF7's + 225 40 18,s,What tyre pressures should I be running?

Just wondered what pressures I should be running as the handbook only lists 17's?
Sorry its in the wrong section Mods but I could wait days for a reply in the wheels tyres and brakes section.
Thanks

On an 04 WRX with that combo I ended up at F/R 34/32 as just right.

May be I am the exception that prooves the rule, I have with the above setup 37psi front 32 rear!
But I like a lot better steering response and feeling from my car!

Not an exception Jim, I ran 34/32 with 18's on a 2004 WRX but my 05 STi with 18's needs 37/32. Less front / rear difference does not seem to work on the 05 chassis.
