Gathered the information all over the topic, and made a picture of my calculator with your curent ST tires and GVWR of 13990 lbs.
Then only 10 % towbar weight or whatever the tonge is resting on.
Because you always have to go from the worst case scenario.
The weights of 10800 lbs you gave can be for instance devided LF 2950 LR 2450 RF 2500 and RR 2900 , so crossed weight differences between the axles.
Then you would think that is way below the maximumload.
But to my conclusion in the topic I already gave link to, you have to substract even 6 LI steps from the ST maximum load to give the tire a yust as save deflection then a LT tire with speedcode Q = up to 160km/99m/h. then only about 2850 lbs maximum load.
The LT tires with 85R16 only slightly more maximum load of 3020 but probably for 140km/86m/h so also for 99m about the same maximum load.

But to law these LT's are not allowed because they have to carry with the 4 of them the GAWR wich is probably 13990-10%= 12598 so more then 4 times 3020= 12080 .
And thats the strange thing here, that tough to laws of nature the LT's can carry yust as much load savely and with long lasting tires, they are not allowed to law.

Someone wrote also 18% pinweight and that is not allowed by law in america as far as I learned, 15% is maximum allowed.

Here the picture with the ST tires maximum load left as its given and then even warning of poor reserve to my standards, and an advice of 83 psi , so a bit above AT-pressure, and a reduction to 65m/h , but that is going from N speedrated 140km/86m/h so this even lower advice speed.
I did not use your low weighed loads , are they for fully filled 5th-wheeler? If you would reduce the maxload witht the system of mine, advice-pressure would go sky high. and only low speed advice.
So a at least F-load tire in same sises LT would be advicable.
But then you have to mind if the rimms are allowed that higher pressure .
