"The F-450 is notorius for strange front tire wear and I'm hoping the beads will help."

I have not found this to be true on my '09. Got 78000 out of first set of tires, and could have gone maybe another 15 if I wasn't headed out on a long trip. Now have 30k more on the new set, and they will go at least as far as the first set. I keep all the tires at 100psi whether towing or not--maybe a little harder ride when empty, but necessary for long tread wear.
Have had the front alignment checked twice since new, and no adjustments needed (4x4). Also still on original brakes at 110k miles.
