Proper Tire Pressure for BFG K02 275/60/r20?

Does anyone have experience/recommendation/information for the appropriate/correct tire pressure? The door jam info would be quite low, and for the factory tires. I'm currently running at 45psi. Wondering if that is too high/low? I don't tow... Appreciate it.

 

My 2014 came stock with 285/55/20 BFG KOs.
It has an updated PSI sticker.



I never ran them at that, I always ran 42 or so.
It would piss me off every time I went in for service they would air the tires up to 49.

I have 275/60/20 Goodyear UltraTerrians now and run them at 38 or 40..
Softer ride with even tread wear..

 

Did the Toyota dealer put an updated sticker on your truck?

 

This is a great tool for getting pressure about right when moving to a different size tire or load rating. And if you want to dial in in further based on your load and rigging, just to a chalk test

Somebody did.
I would guess it was Gulf States since they do the TSS upgrade(?) package.
The TSS package a Gulf States 'port' thing, but I guess it happened in San Antonio and not the dealership...

The wheels are the only 'TSS' thing I have left on the truck..
