Your tires, your money but that's one HE!! of a rough ride! Center tire wear and less stopping ability.
FWIW, the last set of tires wore out at the edge of the tread, not the middle. They were E rated tires inflated to 80psi
What that tells me is you were over the tires capacity. Did you ever weigh it?

2600x6 + 3060 = 18800
Yes, I weighed it.
BTW, I leave my TV tires at 80 because I only ever drive the truck (any distance) with the 5er hooked up. For the few km I put on without the 5er, it's not worth dropping the pressure.
The 5er tires may have been over their capacity but they certainly weren't over their rating. Anyway, I got S637s which are G or H rated (don't remember)

Flashman: I totally agree with Cummins 12v98 on my truck even if it is a 2020 GMC. As far as your question I would put 100 psi and I would purchase a $6.00 tire depth gauge and monitor the wear pattern over next few thousand miles to determine exactly what you need. The tires won't know the difference anymore than your tire personal did and if they are that frail you purchased the wrong tires.
