Correct. And, to be clear, following what the table says, use the highest weight from each front corner to determine the appropriate tire pressure and use that same pressure for both front tires.
The same for the rear. If the highest weight, for example, is the right rear at 9,700 lbs. and the tables say use 85 psi. Use the same psi for all 4 rear tires. I personally will go 5 to 10 over the tables just to be safe.
As has been said. Most blowouts occur because of under inflation
versus weight. Not over inflation.
Check them before you leave, cold, without having driven an inch.
All this banter can be confusing when there are one or two ignorant people with wild theories out there, none of which is supported by a single tire manufacturer on the planet. However, in all seriousness, go by the book and you will have done everything you could have. (short of stopping at every other exit to let air out of your tires......that guy must have a real fun time traveling).
