Have had these tires on a 2003 Dodge 1 ton dually. Average payload is about 4500 lbs. I have over 53,0000 miles on them and there is plenty of tread left to go probably 5000 more miles, but I'm getting a new set to be on the safe side. These are really amazing tires for a work vehicle. Never thought I would get the trouble free miles over 50,000, but I did. Had another set on a F250 - same thing. Get them, you will be pleased.
