erm size doesn't really have an effect on what pressure to run..... 
As for what psi, depends on many things. Vehicle weight, use, load rating of the tyres, rims, comfort, hauling loads, towing, etc, etc.

Draw a chalk line across the tyres front and back, drive a short distance on a dry stretch of road. Chalk left on the outside edges of the tread indicates over inflated.
It's a bit of a faff but you soon get to know what's spot on for typical loads for your particular set-up. It does vary a lot between tyres.
tyres that were on my disco when i got it were 36psi front and 42psi rear, i've changed the tyres now to insa-turbo tyres i think it was (cheap AT ones to get me through). now i ride nice at 32 all round. (i carry a lot of kit in my boot and vary between on and off road use) chalk test is the way forward
