I go higher when tyres are newly fitted, makes sure they seated in well, less chance of rolling off rim off road..then go down to right pressure after a week or so.
Thats my theory, could be rubbish, but works for me
With 31's on 7"rims my Vit is usually at 24 - 26psi on road

i run my 31s at 26psi front and 22 rear...
lots of USA folks run theirs super low at first to "soften" them up... sounds dangerous to me, lol
just let them down till you get a good contact patch on the road (can test with talcom powder or water on the driveway). then go for a highway run and when you get home the pressure should have gone up around 4psi (give or take a bit). if its up more then you're too low.

You dont need any more when the car only weighs 1000kgs. That's also what the tyre placard says

At maximum pressure a single 4wd style tyre is usually rated to carry a load equal to or higher than the whole car, so to make them work with 25% of the load they are required to support you need to lower the pressure

+1 - the 4 psi rule works a treat in my opinion.
