I had load range D tires on my trailer that require 65 psi. They are the right load range for the trailer, but I wanted 10 ply so when it was time to change the tires I changed to load range E which i...

I was told by my wheel manufacturer that if you have 5 lug rims the recommended pressure is 65psi and that 6 lugs are good for 80psi.
I have 6 lugs and upgraded to E tires and run 80psi for the last 5 yrs, with no problems. It dont make sense to me to upgrade to an e tire and not take advantage of the additional load capacity. Running a tire below it's recommendd inflation is more likely to cause heat related failures.
I know there's charts out there by tire manufacturers that state that a tire only needs to be inflated to a point that matches it's load requirement but "hey" they get to sell you a new tire if it fails. I've yet to see any data that says a tire has been known to fail if inflated to the tire manufacturers suggested pressure stamped on the tire.
