Installing Duratrac P285/70/17R on stock wheels

I got a 2013 wrangler Freedom edition as a present for my wife. We will do a bit of off road for sure but never super hard core. assume 70% of daily drive on city roads, 20% highway and 10% on trails. She loves the aggressive look of M/T but I rather have a better tire for Seattle's permanent rain so we are going with Duratrac AT.

The local jeep dealer service manager tells me to go with 285 or 265. My wife would prefer the more aggressive looking 285 but I am hesitant after reading so many posts here about a ride too harsh with 285 tires or some rubbing with the fenders (I am not using lift or spacers).

Appreciate the advice, This will be her b-day present on Wednesday so I have to put those tires on the new car tomorrow after picking it up from the dealer

Go with 285 don't wast your money on 265. The latter is smaller but a little wider than the stock 255/75/17 tires that come on all three models. If you run these tires on the stock wheels you will need spacers (spidertrax 1.5") for $200 a set. The stock wheels will keep the tires to close to the suspension components.

You do not need a lift for this size.

Thanks! Since i need to ask the question you can imagine i cannot do it myself... Is the spacer a major deal to install and will it affect warranty? Or an easy thing that discount tire would do when installing new tires?

The 285's aren't likely to fit without spacers. I'm installing mine this week or early next, as soon as they get here. I'm going to try it just to know but I've already bought the spacers and have every intention on using them regardless. They give the Jeep a better stance. You should call the shop and ask if they have a problem with hub centric spacers. Some shops might think you are talking about the kind that simply sandwich between the hub and wheel, making your studs shorter. Those are the dangerous kind.

Last I looked at spidertraxs.com they were out of normal 1.5 spacers. I just went with the outlet/blemished ones for $20 cheaper. They had plenty of those. Ruff country also sells them for like $60 new and I've heard good things about both. I went with spidertrax because all my buddies who I trust have them and no problems at all plus great reviews online.

I run 285 on stock with no spacers.

I recommend trimming the airdam to avoid rub, then the only time I get any rubbing is all the way over.

Check amazon or quadratec for Spidertrax wheel spacers. I got mine a week ago. Here are a few pics I shot the other day with 285's on.

Thanks!, if it does not bother you much, would you be so kind to share a picture of what I need to trim?

Thanks for all the help

Every time this subject comes up there are those that say you need spacers to run the 285/70s on the stock wheel. That is not true with the new JK. I don't know if they have heard this here, as it is repeated all the time, or were told this by a shop or dealer wanting to sell them spacers or after market wheels with less back space. The real answer is... you do not need to do anything.
My 2013 has 285/70s on the stock wheels without spacers or a lift and the tires do not hit anything. Full lock turn is clear. No need to use spacers there to limit the turn.
The 285/70 is generally just short of 33". About 32.8 or so. This is only a .4" increase on either side of the wheel and is not enough to cause a problem. The increase in width is not enough to cause a problem either with the minimal increase in diameter.
No spacing, no shimming, no trimming as long as you are not planning on extreme disconnected flexing (it doesn't sound to me like you are). If you are then you may need to trim a little off the airdam or simply level your front by lifting 3/4 of a inch or so (looks better anyway).

Thanks! very useful, and thanks to ChiefDan for posting the pictures on his profile (airdam trim). wheels ordered and I will share pictures once my wife gets the gift tomorrow am... cant wait to see her face (and the face of our son) when they see the car in the garage.

Thanks, Marc! I didn't physically check, and sometimes the internet is full of (gasp) misinformation, but do the new Rubi wheels have the same specs (size, offset) as the Moabs previously used on the 2012 and older Rubi JKs? If so this is good and bad news for me as I already went with 265s to avoid rubbing and I didn't want spacers or a lift for now. Of course, some tire makes labeled the same size are sometimes significantly physically larger/smaller which adds some measuring fudge.

People (here) get it from the FAQ/Sticky about "how big on my JK". (Or other sites)

If you check the conventional wisom on the JK, most of the FAQs say "should be able to" or "may need a spacer" or "may need to trim" or "may not stuff" or whatever. This is due to the variables in tires, tire pressure, model years, models (JK/JKU) etc.

That's why it's a "Your Mileage May Vary" situation, I think.

I plan (note plan, I'm still not sure) to run this tire in this size on a 13 Rubicon lifted 2". (The lift is for hanging bumpers and a winch and pulling a trailer and hauling my gear and my fat dog, so I'll probably end up back at stock height when I'm done)

It should work, but if it won't, I'll have to give up the stock wheels (that I happen to like) for some with 4.5 BS.

Correct me if wrong but I think the older Moabs (17") are just painted 17" JKs and until 2013 the Rubicon wheels were the same as the rest.
The new style Rubicon wheels have the same 7.5 wide with a 6.5+ inch back space as the 2012 style.

I have also seen where the different tire mfgrs have slightly different dimensions for the same size (285/70-17) than others, so unfortunatly nothing is exact. Also, some tires that are labled as "33 inch" may be significantly larger than a 285/70 so that could be where some of the mis-information comes.

The only actual experience I can personally speak from is that I had a 2011 2-door sport and now the new Rubicon and I have had 285/70s on both of those.
On the sport I used a after market 17" wheel with a 8" width and a 4.75" BS. This back space moved the tire outward by 2" and placed it under the lip of the fender. So instead of the tire having the space up inside the fender well, it could (and did at the rear under full compression) make contact with the lowest point of the fender (the lip).
With a 285/70 that doesn't have any inside frame or suspension issues, you'll get more compression travel by leaving it inside the fender than by moving it out with a spacer or a reduced BS wheel.
Like I have said... this is from my personal experience and not from hearing it here or from somebody wanting to sell me something.
I do not have experience with 34" or bigger tires so I'm not going to guess where the limit is.
One last thing... depending on what springs yours will have (my '13 Rubicon came with 14 fronts and 56 rears) you may see a nose down attitude in the front. About a inch or so is normal. I have now placed 3/4" coil spring spacers on the front and it is level (easy job). That looks better in my opinion. Hope this helps.

Yes the Moabs were used on Rubis and were the upgraded wheels for the pre-2013 Sport/X JKs. Good to know that the new 2013 17" Rubi wheels are the same spec as the 17" Moabs.

UPDATE-

Just had the 285/70/17 installed, it works perfectly w/o spacers on stock wheels.

PSI seem high for me at 36... what other Duratrac 285/70/17 owners are using (PSI wise) I am thinking of going down to 33-34

People aren't crazy nor are they spreading misinformation. Perhaps just guilty of not giving the full story. Truth is, not all 285/70/70's are created equal. Each brand and model can vary. Width is the rubbing issue on JK's not height. Just because your tires fit without rubbing, doesn't mean everyone's will.

I would try 30. I had mine at 35 and went down to 30 and the ride was much better.

285 70 17 Duratrac are good on and off road. I run mine at 34 psi on stock 17's. I also have a 2.5 lift and they almost look small on there. No spacers are required. The tire overall is great. This comes from a guy that lives in Northern Alberta, Canada.

Agree.

Some 285s will not fit correctly without spacers. Depending on the wheel backspacing and type of tire mounted, some work some don't.

People who have fitted 285s without spacers also have not fitted all 285s out there available. Different 16 or 17" wheels & tires mean different results.

The truth is you may need spacers, just depends.

Love your White Oscar Mike. I have a Billet Silver 2013 OM. Your pictures are great since I get to see the tires on my exact wheels, color and all.
Thanks,

I just put a 2.5 TF budget lift with shocks on my 2012 and was told that I needed 1.5 wheel spacers for sure to run stock wheels and tires.

And I am. I guess if I go from 255-17 to 285-17 then that means I can take the spacers off.

No.

You need the wheel spacers in this instance for the lift. TF and a few other 2.5 lifts out there require that you use wheel spacers with any size tire and their lifts when still using the stock wheels. This allows the wheels to clear the extended sway links placed in the front. If you don't run spacers, they will rub the links.
