30 psi all round... non PAS though. Depends on the condition/make of the tyres too; on old tyres the rear grip was non-existent whatever the pressure, 30 psi on new Continentals is fine.
One of my rears went down to 15 the other day and it got a bit loose at the back.... back on 20 and all is well. (On the 400SX I use 20 all round because the rears are 245's)
