I have them on my 04 f-150 because my wife bought them while I was offshore, I have 40,000 on them and over half the tread is left, but i have regretted them since day 1 as they are the roughest riding tires I have ever owned, I have tried just about the whole range of air pressure from 25-45 with no change. I also had them re-balanced thinking that may be it. Im just waiting to put some Coopers or Goodyears on it in the next few months as the truck rides well on the Goodyears but they dont seem to last as long. My 01 company truck had the michelins and we got 90,000 out of them but they rode rough on that truck as well.
