225/40 R18 - 38 psi all round but that's on a barge (read Liberty).

Could I also suggest you don't have to start a new thread for every question you have.

I'd also not take lessons from Raj ... He's a bit thread start happy as well.

I was told 37 all around on the same sized tyre by Bob at wheels world a few years back. Works for me.

I run mine at 39 psi front and rear with the yokohamas, when i had bridgestones i ran 37 front and rear.

You should be adjusting tyre pressures on the street based on the tyre wear. If it is wearing on the outside edges increase the pressure and if it is wearing on the centre of the tyre then lower the pressure.

So this thread pretty much confirms what I already suspected.. Which is that almost everyone has a different idea of what tyre pressure is "ideal"

May I ask why? It's easier than searching every post on the site to find a simple answer, and plus some posts I've seen date back 5+ years so the info might be invalid. Don't post's gets deleted after a certain time frame anyway?

You're right, tyre pressure info from 2009 is irrelevant in this day and age.
