As a rule of thumb, maintain or increase the pressure you're used to. The lower the sidewall of the tyre, the higher the pressure needs to be to make sure the rim doesn't hit the tarmac. PSI means nothing to me, but it should be at least 2.1 bar, but preferably 2.3 or higher all round. If you're having long trips with people, luggage and high speeds, add some more. Tyre blowouts occur most often when the pressure is too low, increasing friction, ending in failure.
