Those psi ratings are very low. They do not specify load or speed. I have another SUV that has low tire psi ratings too. That vehicle handles better and the tires wear evenly and last a long time when I run at higher pressures.
I'm looking for someone who might drive at legal speeds for longer distances on highway or someone who travels with a vehicle loaded with a lot or gear and might have a recommendation for tire psi.

Never, NEVER go by what it says on the sidewall of the tire.
Tire's on your 4R fit many trucks and applications.
Like Grant says, read the label, it is what the manufacturer of the vehicle recommends for PSI for those tires and the GVWR of the truck.
I've been running a fleet for damn near 30 years and know a little about tires.
But.....I have the same tires as you and run them at 4 psi over the label; 36 vs. 32.
I get better wear and mpg, been doing that for years on all my vehicles.

Plenty of load reserve at 32psi. See the 2nd graph in this thread.

I'm going to run 35 or 36 psi, seem more resonable. I have MB ML320 and while not same size tire I run 36psi in all four of those tires. The first set of Dunlop Grantrek tires lasted about 30K miles and then the next two sets of Michlen Cross Terrain lasted about 62K miles. I'm now on my 4th set of tires which are Bridgestone Dueler Alenza H/L.
