It appears the GY Endurance max psi is 80, so would I have to get different rims that would allow higher psi?

If they are 5 lug wheels, they are rated to 2540(D), 6 lug rated to 2830(E). I did the same tire upgrade on our 2019 Laredo with a 8K GVWR and run them at 71 PSI. Our wheels were rated for LRE tires.
Just finishing up on our the first half of the second round trip to Az from the NW. So they have around 5K miles on them.
The pictures that I could find of your model appear to have 5 lug wheels!
The E rated tire in the same size carries the same weight at 65 PSI as the D rated tire, so I add a little more for good measure. You could go to the LRE tire and just run it at 65 PSI which is 10160 lbs of capacity for four tires. Your GVWR appears to be 9500 and part of that is tongue weight. They did not do you much of a favor if it has the 5 lug wheels. Chris
