I found out the hard way on my 1996 Yukon that there's one more important set of components that have to be checked.
I'm running 285/75R16's on a stock SLE. At some point in the past, the right front bump stop, or jounce bumper, was damaged. Someone (perhaps a body shop mechanic repairing a fender bender on the right front) realized the truck wasn't sitting right and jacked up the right T-bar to compensate.
So, under virtually all normal conditions (and even in some extra-normal conditions) I didn't have any rubbing issues. But when I got in some really severe conditions, the lack of a proper bump stop allowed my tire to hit the fender opening; even though the T-bar was holding the truck up higher under all other situations.
One of the things I learned is that the bumpers are an integral part of how the front suspension works. Check yours to make sure they are in good shape to have an extra margin of confidence your rubbing will be minimal and minor when you're on two wheels making a hard turn up a 30 degree incline.
