I've got the 10 plys (load E) and they came off my '09 F150 when I traded it in. They had about 80,000km (50,000 miles) then and they have at least another 20,000km before they are getting to change time. I rotate every 10,000km and run at 32psi. HIGHLY recommend these tires!

I've put just over 11k miles on mine. If I had to guess by how they've worn so far, I'm going to get around 50k out of them. For what it's worth, I rotate all 5 every 6k miles.
