As for whether a rim can handle the 80 PSI of a E load range tire, the best way to check is to look inside the rim or check the manufacturer's specs. However, here's something I noticed: 65 psi rims have 5 lugs; 80 psi rims have 6 lugs. Maybe there are exceptions to this but I have yet to find one.
The rims on my old Dodge 1 ton dually had 8 lugs. The truck came from the factory with Load Range D tires. I installed Load Range E tires, one size larger than the data plate called for. Oddly enough, the larger tires corrected the speedometer error!
I have no idea what the pressure rating of the rims was.
In the past, I owned several old Chevy 6 lug trucks and cars. I really doubt if those rims were rated for 80 PSI!
