snookybell, the only rubbing I have ever experienced has been on the right side front when backing up with the wheel turned hard to the left. There is a plastic liner behind the front bumper that rubs ever so slightly. I could probably find a way to tie it back but it really isn't worth the effort. My fuel mileage is probably not much different from stock but I have also made a few other mods so it would not be easy to compare to stock anyway. I had these tires installed by the dealer so I never drove the truck with the original tires. Approaching happy 14,000 miles.
