Tire Pressure?

Ok. Tire markings say max loads are 3305 used as a dual, 3525 as a single at 110 PSI. So I have a lot of headroom there. Tire type is 124\122M 12PR\LRF which seems to mean it can be used as either a truck or trailer tire.

I think I'll inflate them to the axle max, not the 110 PSI. 110 PSI seems like overkill. So I'd be inflating to 2000 lbs in the front (4000÷ 2) and 1600 in the back (6400÷4). That is until I can get it properly weighed.

whats on the tire 12pr/LRF and given AT-pressure of 110 psi dont match For this description it should be 95 psi, but there are exeptions in that system.
Can be that they are special camper tires C/CP and for those Michelin gives only maximum pressure and not AT-pressure.
So look again if in front of 110 is written "max pressure"or "AT"
Not even sertain so I will go from the maximum loads given AT 110 psi in my made spreadsheet.

Have made a map in the examples map on my one drive public map with your username turbojimmy.
You can download it to your computer or open it to look in.

And here a picture made of it and gives Front 62 and rear 59 psi advice . When AT pressure apears to be 95 later advice will be lower even.
But also lowered the Loadindexes by 4 to get deflection of tire that belongs to 99m/h and this gives highest to fill advice , higher gives bumping and gives Front 71 and rear 67 psi advice pressure .
With these advices enaugh reserve for overloading and unequall loading, read the information below the pressure advices.

Sorry I cant include a picture because those St*&^%d American One drive that belongs to Hotmail have chanched the system again so have to find out how to do it again.
But open the map and you will see it
