Well, without trying it or knowing someone (or by slight chance finding)who has done it, you have two choices...first would be to find a friend nearby with a 31X10.5 on a Nissan rim. Jack up their truck and take one tire off...and then take one of your fronts off, and put their bigger tire on. Then turn the wheel lock to lock, and check the clearance inside the fender (and of course don't forget that the tire will move up and down inside the well, especially if you go off road, so make sure it will clear above and below inside the well!) If you are satisified that it won't rub, then you should be okay.
Way number two would be going to a local friendly tire store and having them mount a 31x10.5 and put it on while the trucks on the rack...and then do the same tests. They will tell you if it clears...and if it doesn't they will probably be more then willing to see you the biggest tire that will clear! (laughs)
If both of these seem to be a pain, the only things you can do is try to find someone at Nissan that knows (call your dealer, and they will probably give you someone else to call) or call a knowledgable tire store (not Sam's, but someone like America's Tire) and see if they could find out somehow for you. Good luck and happy off roading!
