You can run 285/75/16 or a 285/70/17, but it requires the following to avoid rubbing when turning:
-small lift (I think)
-either new wheels with backspacing or some spacers (for instance, 16x8 with 4.5" BS)
-removing mudflaps on the front
-trimming fender area
-possibly relocating the front body mounts
remember, this is to avoid any rubbing issues.
After a guy sent me this article

As for tires, what type of 'wheeling?
This is a big question you need to ask, but I'd also throw out 'how good are you', and 'how hard do you go'?
One of the club leaders for my 4x4 club wheels an FJC with BFG A/Ts, and he's had success through difficult TSF trails, Rubicon, and Moab, among other places. However, he's a very skilled driver (he's published
), and I don't think he'd try those tires if he was straight mudding.
Here he is on the BFG ATs, which were ready to be replaced. It was super wet and muddy that day, but he made it through. Keep in mind the pic makes it look easy.
I've taken my Rugged Trails through moderate trails (and a difficult rock garden) at TSF and have made it through, though it may take me a few extra tries or heavier reliance on the locker. Being utterly new to 4x4, I'm still able to keep up a decent amount.
It's no secret that the Rugged Trails aren't great for offroad capability, so don't buy them... but if they came on the vehicle, that doesn't mean you have to rush out and buy new AT or MT. It just means you might need more finesse or might get extra help on some of the more extreme things you do.
This is me on a moderate trail (again, pic makes things look easier... maybe this was just an easy spot
