Have put your data in my calculator and gave next picture .
Below that I will explain further.
Made first calculation for your GAWR's with the reserves I think are the savest. Gave F88 R82psi.
Then filled in your given real axle loads ( but are those realy the loads in your use as someone already daubted), and gave F73 R77.
But these advices are for the speed of 75m/h as Goodyear uses in their list and most likely Bridgestone too.
So the picture gives last calculation in wich I lowered the maximum load to give the tire a deflection that would be needed for 160km/99m/h, and then even noticed that the S/D given was only 1 LI step difference, wich is not to the European system of 2 steps , America even sometimes uses 4 steps back.
So I corrected that to my opinion false information, and this gave the advice from the picture=
F82 R 89psi .
Whit these pressures F370 R755lbs combined underload and weightdifference R/L possible with acceptable gripp and comfort, yust no bumping expected and maximum reserve for things like .
Incidental extra load.
Misyudging of load and inacurate weighing.
Unequall loading R/L wich can easyly be 200lbs and even crossed between the axles.
Misreadings of pressure.
Pressure loss in time.
etc
etc
Also calculated for 75m/h and gave
F73 R80 psi .
Wiht these pressure still combined unequal load and overload possible of F555lbs and R1135lbs before damage to tires when realy driving 75m/h, wich I think will be absolute maximum speed you wont go over for even a minute.
So keep your cold pressures between the fat printed, and if you fill , fill them to the F80R89, even though you will never drive 99m/h.
Put 3 pdf's and this picture in map with your name on it here.
Also added the spreadsheet filled in with 75m/h advice.
If you download that to your computer you can open it in Excell ( or likewise programm) on your computer and play with the values yourselfes.
You can download KRex map or open it
