I typed a response but then realized it was pointless. Have fun running around in your new HD truck with 80psi on all corners so you can lift a tire.
I don't think I've been overly antagonistic in this back-and-forth. I have genuine questions about the literature you're referencing.
Are you allowed to "overload" the tires beyond their rated weight capacities at certain speeds?
Are increases in tire pressure required to accommodate those 'overload' scenarios?
If you want to give me a genuine answer in return, I'm all ears. If you prefer to stick with snarky responses, well have a nice day...
