You can run an E rated tire at 65. When I had my F250 and F350 I rarely aired them up to 80 PSI. You sure as hell don't want to be daily driving either D or E rated tires at full PSI, unless you want your teeth rattled out of your head. lol
Determine the load you'll be carrying, check the tire's inflation load chart (most manufacturers have these specs on their websites). A D rated tire at 65 PSI is for max load, but even at 50 PSI it'll carry a higher load than a XL tire at max pressure.
I run my D rated tires at 40 PSI daily and only air them up to 65 when towing my travel trailer. I don't bother airing up when towing my bass boat.
Oh yeah I'm sure that would suck lol these are going on the back of a halfton truck for stability while towing roughly 7500lbs of tongue heavy camper with some dogs in the cab. Load range really won't be an issue, i'm sure i'd end up staying in the 40-50 psi range then. Mostly just looking for as much stability as possible to help further mitigate sway.
This is good info as i'm thinking I won't need to worry about messing with the stock valve stems then. Been running 50psi in my XL tires for months with no issues.
