Have put the data in my calculator and made picture of it.
Also read the extra information below the pressure advice.
But assumed you weighed with all the luggage and persons in it, otherwise your axle weights in use will even be higher.
The front pressure advice gives red in both value and pressurekind, because advice is higher then even American tire makers allow for LT tires .
For Truck tires , wich your tires in fact are, they allow 20 psi higher .
So front 125 psi advice for up to max speed of tire of 120km/75m/h,as I searched back on Michelins site at the specifications.
And rear 113 psi. Here only pressure kind is red because within 10 psi above AT-pressure, wich is not the maximum allowed cold pressure of tire.
For maximum pressure with still no discomfort and still good gripp you can even use higher pressure.
So my advice for the loads you gave is 130 psi front and 120 psi rear , for maximum reserve without bumping. This is what most American tire makers still alow.
But all write that the rimms must be allowed that pressure too, and its given on inside of rimm so you have to get one wheel off or if spare is the same look at that.
What is given is cold pressure , higher pressure by higher inside tire temp is calculated in the specifications.
so my idea is better to use the high pressure , even if rimm does not allow it, better neglectable chanche on rimm leakage then tire damage with blow out and accident and injuries and damage.
Best is still to get new tires and axle upgrade and eventually new rimms , and or do some weight shifting , rear has some reserve, but for now you have to do with the things you have. If you give GAWR's and GVWR , you will see if they have some reserve.
Here the picture.
