I'm running 285/70/17 Duratrac's and a leveling kit and have since the truck had 300 miles on it, so I can't compare mileage. Hopefully yours stay quiet for you because mine with about 20K on them have gotten really loud. They had 8K on them when I installed them and they sounded decent until about 2K ago and then started to really howl. They still seem to drive and ride nice though, with no vibration or pulling so I can't complain about that. I got 16.7 mpg on a recent trip from Colorado to New Orleans with them inflated to about 52psi. The return trip was pulling a 4,200 lb trailer and going uphill so I felt lucky to get 13.1 on that leg. Also that trip was in the summer, so we had good gasoline at least. The truck is a Hemi crew cab 4x4 with 3.92 gears and running 75mph at least the whole trip.
