The pressure rating should be on the door sill, or use the rating on the tyres

You can calculate it with spreadsheet I made with use of the same formula, the car-and tyre-manufacturers in Europe use

If there are questions , ask them here.
Mind that the front axle seldomly gets overloaded, the rear-axle almost always. So calculate with a load-percentage Front 95% to 100% and rear-axle 85% to 90% using the Gross Axle weight Ratings ( GAWR).
You only have to collect some data of your tyres and car.

Afterward you can see what the inside-tyre-temperature does to the pressure.

what???????

You can yust calculate it.
But if you have the same Fiat Ducato 14 as I had as camper,
With Gross axle weight ratings Front 1550 kg and rear 1700kg
and tyres 185/75 R 14 with load index 102/100 wich means 850 kg max load per tyre for single load. the advice of the factory would be
4 bar front and 4.5 bar rear( in case "at 450kpa"on tire side wall). My advice for rear would be higher say 10% more for rear. But if the load realy goes over the GAWR rear you may not drive faster then 100 km/h with 5% overload and 80km/h with 10% overload.
But ask me more then "What?????" , give me details
