Anyway, I removed both of the rear driver side tires and both have nice big bulges in them under the tread at one point. I'm guessing this is a result of the plies coming apart. So I will be going to get two new tires. My plan is to swap the two old front tires to the back with the other two good old tires and put the new ones on the front. How does that sound to everyone? I know matching tires on the rear of a dually is important. Thanks for the help everyone!

That's exactly what I would do. Sounds like you found your problem, let us know how it works.
