Yes. That is correct, to a point. I believe it is unreasonable to list loads that cannot be carried at highway speeds. I also think it would be difficult to explain those precise nuances to most folks, including those who might give you a ticket for exceeding the weight rating molded on the tire sidewall. Increasing pressures above the listed maximum is normally limited to 5psi and 5mph and applies predominantly to ST rated tires
In any case, that is why I gave both the size tire and the specific inflation pressure posted by Goodyear, which exactly comes to 5400 lbs. times 2= 10,800 lbs which is what AAM rates the 11.5 inch axles under Dodges and GM light trucks for -- 10,800 lbs. You could actually go down in size to a 255/70R22.5 and up in load range and inflate it to 115 psi and have exactly the same load rating -- 5400 lbs.
