Tire Size?

I think i am correct but the largest tire size i can run is 285/70/17? I have a 2012 jku with 1" front leveling kit. I want the largest tire size possible without causing any rubbing issues.

There is a FAQ up top with all kinds of information on tire size and rubbing.

Unfortunately, NOWHERE does the FAQ answer this question.

He's got 1" lift in the front only, if I'm understanding correctly. And he's using 33x11.50, not 33x12.50 which is generally what you're talking about when you use the term "33s". I don't see that combination in the FAQ anywhere.

Honestly I'm looking at running 285/70-17 on my stock wheels with no wheel spacers and only a leveling kit myself...and I've been trying for 2 months to get a straight answer on whether it'll fit or not with no success. So I feel his pain.

are you talking about running these tires on a stock wheel?

I'm running 295/70/17s w/ aftermarket wheels. 4.5" Back Spacing and -12mm offset. No lift what so ever. no rubbing issues. However if i really dig deep, it does tend to barely rub at full lock when turning in reverse.

Yes i was going to reuse my "Premium 17" Wheels". Right now the jeep has the stock 255-75-17 tires.

Anything wider than about 10.5 inches will rub on the front sway bar when the wheels are turned to full lock. The rears may also rub when the suspension is fully compressed. You need to either use wheel spacers or get new wheels with less back spacing than the OEM 17" wheels. About 4.75" effective or less is the sweet spot for running 285/70-17s in my opinion.

Or use your current wheels with 1.5 inch spacers to run 285/70-17s. May rub a tiny bit on the front air dam or the rear fender flare but they are plastic and at least in my case the rubbing hasn't done any real damage.

The stock 17's don't have enough back spacing fur the 285s. Also, keep in mind that a lot of tire shops will not perform work on a vehicle that has wheel spacers. So if you need a tire mounted, you'll need to bring your own jack and wrench to remove the wheels for the tech to mount your new tires on them.

I see a lot of talk about "some rubbing" or "a little rubbing" with 285 70r17's. How much is some or a little? Is it going to keep me from driving to work, or even across a mild trail? Does it rub before full lock, or only at full lock or stuff?

I'm really considering the 285's as well and I don't think I really see anything that gives information on how much rub and at what point.

I am so glad you all are discussing this, while there are a lot of answers in the FAQ section, I have been unable to find a simple clear cut answer to the question I see repeated here on the forum over and over. I am not a complete idiot, nor are my jeeps used to go to the mall. I have an 04 Rubicon that I use off roading and serious trails, i.e., Moab Utah etc. I have a newly acquired 2012 4 dr that will be used to tow one of my other toys, a John Deere Gator, on the beaches for fishing. I would like to change the original stock tires without any other modifications to the jeep. So I ask the same question, what is the largest size tire I can use without them rubbing? I plan on using the original wheels at this point, but I am not against changing the wheels but am not looking to do a lift.

Thanks

Rubbing is mainly at full lock and stuff in most cases.

The reason why there isn't a clear cut answer is because tires are like shoes. Some brands can have a tendency to be slightly wider or taller than others.

To be on safe side, have a set of wheel spacers on hand if needed.

You can run a 265 without issue or you can look for a narrow 285 (aka: pizza cutter) but your brand selections won't be as good.

If you're running on factory "premium" wheels, 285's is probably going to be your limit and whether or not you rub (and how bad) is really going to depend on what tire you get. (Stock Jeep with no lift looks really good with 285's...)
I ran 285's with aftermarket wheels that had 4" of backspace with zero issues. The stock wheels, you might need to adjust a steering stop a tiny bit, maybe trim some rubber to keep from hitting the swaybar, it's really hard to say. You may have no issues with your driving style.
Even running 35's with a 2/5" lift, I still hit the inner fender well when I turn to full lock to back out of a space.
I did a few trails with the 285's and stock suspension with zero issues, so wheeling shouldn't be a problem.
Be careful if you decide on spacers. Some places they're illegal, and as already stated, most shops won't work on a vehicle with spacers. All depends on where you are.
