I have a total of 8 original rims with the very same tires you plan on going with on two trucks.
As Kevin mentioned, the bead seating area needs to be smooth and not pitted, and you need a sound valve stem hole. If you don't have a sound valve stem hole, you can drill a new one and weld up the old one.
Another problem area is were the 2 halves of the rim is riveted together.
I sand blasted all of mine and epoxy primed them, and I strongly recommend that. Once you they are primed, I used 2 part epoxy on the rivets on the inside of the rim for insurance. My tires have not needed air for many years.
