E rated tire with max psi of 65?
I have Nitto Ridge Grapplers that came on the truck when I bought it used, size LT325/65R18 E 127/124Q. Every E-rated tire I've ever seen is rated to carry its max load at 80psi, so the first trip ...

Well I'm feeling pretty lucky right now...on out 1000 mile road trip to PA in October (maiden voyage with the newly-rebuilt camper), I had the rears aired to 80 and was seeing the TPMS tell me 85/86 going down the road at 70 mph. I'm thankful they didn't blow running that much over max.
The flip side is that I'm sure the extra air helped with stiffness and stability...so maybe they would squirm more aired to only 65?
Here is the specs page from the Nitto site for their Ridge Grappler tires.
I've added some notes:
A- This is the size that Ram puts on the truck as OEM. My truck has 18x8 rims.
B- This is the size that's on the truck now.
C- This seems like a good choice for a replacement when these wear out.
