Go back to stock wheels... find some, period. Make sure truck runs as it is supposed to there, and then figure out wheels. Start with wheels and make sure they spin true without balance issues. Also make sure center bore is center to lug holes... I know that sounds like WTF, but I have personally owned high quality Weld wheels that were off and when lug centered, center bore was off by a mm. I've seen a lot of weight on Super Swampers, but Toyos are good tires and shouldn't require much weight. Did you have an alignment done initially??? That could be off. I personally LOVE ceramic beads in tires. I have used them in all truck tires and they are awesome on the street. I don't know what noise you would be concerned about. There is no bead noise you will hear over the Toyos.
...one more thought... Are tires rubbing spindles?

Just read initial complaint and the oblong rotation of wheel stands out. Wheels are made lug centric... try running them that way and see what happens.
