Hi Jim
Thanks for position the link to the Toyo tire pressure information site.

The best information I have found on correct tire inflation pressure is from Toyo Tires:

That is the exact same .pdf I used to calculate my tire pressure based on my CAT Scale printout.

Here is the updated PDF for 20170203

If you are changing from a P-metric to an LT-metric tire and don't want to read a lot of information go straight to page 11 of the Toyo reference that so many have pointed to.  It is pretty straight forward information.  Heed their warning or pay the consequences.

 

WARNING! Please note that size-for-size, LT-metric tires require higher air pressures to carry equivalent loads of P-metric tires and that any failure to adjust air pressure to achieve the vehicle’s load requirements will result in tire fatigue and eventual tire failure due to excessive heat build-up. Due to the higher PSI requirements of LT-metric tires they may not be suitable for replacing O.E. P-metric tires because of the ride harshness that results from higher PSI requiremen 

 

Spend a half hour reading this information and you will be safe and good to go!  Thanks to other members who pointed me in this direction.

I have a Fleet Shell on a Nissan Frontier.  Switched from stock to BFG KO2s (E Rated).  I messaged with BFG on their website.  I gave them the truck, load and front and rear axle weights loaded.  They recommended 50 psi loaded.  They also reminded not to go below 20 psi.
