I've never got more than 30-32k miles on a set of tires for my F350. That's with the factory Michelins or other brands. I'm not exactly easy on them with hard accelerations and heavy towing. I just settle on using the warranty and getting nearly half credit on new tires every 30k. I've run the Nitto Terra Grapplers 2s at Discount Tire. I have the LT295/65R20s that have a 4080# load rating and a 50k mileage warranty. I camp offroad a lot in sand, so the the all terrain tread works well. I routinely see 7600# on my rear axle of my truck with the Montana hooked up (3800# pin weight)
