In any case, Toyota even agrees that LT tires need more pressure. There's a service campaign to replace TPMS modules on TRD FJ Cruisers (They came equipped with optiona LT Tires) because of a higher tire pressure being needed and the baseline P rated tire minimum programmed value being too low (don't ask me why they just don't reflash the module... its Toyota, they haven't been very flash happy in their history...)
Perhaps we need to scrap what we're arguing about right now and start from the ground up. What are the differences in the construction of P, LT, and Commercial tires and how does this affect the tire's flexibility, load, then go into the air pressure. I think that might help allievate confusion.

6300 pounds is the GVWR - the vehicle, fuel, passengers, cargo, everything. I don't remember the curb weight off the top of my head, around 4700 pounds if I remember correctly.
I agree w/ extra pressure, at the very least you've got to go up to 35psi, but beyond that you're going to have to experiment a little.
