OK, sounds good about 35's then; would this be what I'd want to order? I looked up the tire at BFG site (shows as 34.6" diameter) and then google:
BF Goodrich All-Terrain T/A K/O - LT315/75R16/D (RWL)

..not sure if that is a good merchant..came up during search.. I wonder if I could order them through my Hummer dealer and let them take care of the wheels, mounting, everything.
Also, this would fit standard stock wheels, right? One more thing - would tire of this size fit the gate/mount? I would prefer to have 5 identical wheel/tires, carrying the full-size spare on the gate. Sorry, many questions...newbie here. Thanks for understanding!
