Question about tire pressure

You and several others here have referenced a "tire inflation chart." I cannot find one from Nitto, which is why I wrote to them.

The tire inflation chart I linked will work and will be within a few pounds of the inflation chart Nitto has but may not be willing to release unless you get to the correct techi. You can thank the liability lawsuits for making it hard to find the charts since they just want the average driver to use the numbers in the door jam. Reason any chart will work is that it is physics that determine how much weight a certain size and psi will work. They don't test every psi to get the loading, they use a formula. The only real difference between different manufacturers is the safety factor and minor differences. Look at multiple tire inflation charts that are available and they will all be almost identical for the same size and load range of the tire. I only referenced the Toyo chart because theirs is the easiest to find. Michelin wasn't even willing to give me the charts, but at least I managed to get hold of a tech who was willing to verbally call out the numbers for my particular tire size which exactly matched the numbers on the Toyo chart.
