I went with the 285/75/16s today. Having 4.10s in the rear end and hardly ever ever pulling anything, I wanted to gain back some rpms on the highway, and give my engine at least *something* to work it some.
I have some rubbing on the front bumper, which I was suprised at, so I'll start another thread to deal with that after I search the archives of course.
Thanks for all your help on the tires.
