Someone else PM'ed me recently about whether 285/75R17 tires will fit without rubbing. Reposting my response to them since it seems like it may be helpful here:
Short answer is yes, they will rub, though you can minimize it with a little effort. I have a fairly lengthy thread where I put 34s on without a lift, did some trimming and tweaking, then eventually caved and just did the lift.
This week I swapped out the stock tires and wheels with 34s (Nitto Ridge Grapplers in 285/75R17) and Icon Six Speed 17" wheels with +25 offset. I also added the 3/8" Toyota front spring spacers, which gave me a small boost in front, but not quite as much as I expected (or maybe it did, but with...

If you don't want to read the entire thread, my summary is you've got 3 options to minimize and/or eliminate the rubbing, depending on how much effort you want to put into it:
1. 285/70R17 with +50 offset (Rock Warrior) wheels shouldn't rub at all.
2. 285/75R17 with +50 offset (Rock Warrior) wheels. With some careful alignment this should be able to fit without rubbing. YMMV though and you may need to still implement a portion of the options below:
3.. 285/75R17 with +25 offset wheels. The rears are fine. Up front, you will find with +25 offset that the wheels take a bit wider arc when turning, and because they sit an extra 1.25" outward the wheel well shape is now "inset" and thus you'll rub in a few spots which are closer to the body:
- Remove the mudflaps (easy)
- Pull back the plastic liner where the mudflap was and use a hammer to push the mud flap mounting bracket inward a bit (not too hard, but it's difficult to reverse if you ever decide you want to put the mudflaps back)
- Use a heat gun (or hair dryer) to warm the plastic liner in the rear part of the front wheel well and then reshape it by pushing it inward (easy, takes a few minutes, no negative impacts)
- Remove the tiny plastic "air dam" in the front of the wheel well at the bottom (2 small bolts). (easy, no real impact)
- Trimming of the front part of the fender liner may be necessary depending on the alignment. (not too hard. not immediately reversible, though you could always replace the liner in the future if you ever wanted to go back to stock, as they just pop out with a few clips)
One place where many people rub is the inside edge of the KDSS arm. Some folks also rub slightly on the same edge of the sway bar on the passenger side. A good alignment tech who knows how to adjust caster can minimize this, though whether it can be easily eliminated is TBD. I run a lot of caster in my setup so I rub on these 2 spots, but only at full lock (e.g. when parking). In my case I just put up with the slight rub and back off the steering wheel very slightly if I feel it. If you want to eliminate this issue aside from alignment adjustments you may need the KDSS relocation bracket. They are ~$100 and not too hard to install, though they may leave your sway bar end links at a steeper angle which can cause faster bushing wear. There are some possible options for this though I've not personally tried them... yet.
