So I have read through here a lot and I think I have a basic understanding of this.

I have a stock 2012 Rubicon 2 door. I bought some XD Rockstar rims 17x9. I believe that I have about 4.53 backspace or something close to that.

I am trying to avoid a lift right now and mostly an on road driver with a little bit of off-roading at the deer lease or my grandparents farm...nothing too extreme. Anyway, I have the stock 255 tires on right now and am looking at going to the Duratec 285/70/17 tires.

Am I right in assuming that with the backspace provided by the new rims, that spacers wont be needed? (im just assuming for the conditions I listed above. I would gather that if I want to disconnect the sway bar, that there would be some fender rubbing)

Anyway, thanks for the help and hope im not repeating what has already been asked before

So....I studied and researched this topic of 33's on a stock JK. This thread, by far, was the most informative and when I walked into Discount Tire the other day I felt like I knew my sh## and was going to be able to tell them what I needed for my stock 2012 JK sport....wrong!! I told them I wanted to run Falken 285/75/R16's on a black 16X8 wheel that has to be 4.5" or less back spacing. They told me they figure the back spacing differently and assured me the wheels they ordered would work fine . But now I'm nervous about it. The wheels I ordered are Level 8 Tracker 16 X 8.5 5-127 -6MTB. What in the heck do all those numbers after the 5 (which I get as the bolt pattern) mean? Will these work without modifications? I've owned Jeeps for quite some time but I'm a rookie at going beyond stock.....and I'm a girl....

5-127 is your bolt pattern. 127 is 127mm, or roughly 5". So 5x5" pattern. -6 is the offset or backs pacing. MTB is short for matte black finish.

Sorry, should have finished this. -6 is an offset number measured in mm. Your backspacing ends up being "roughly" 4.25". I'm no expert, but that is how I understand it.

Thank you for explaining those numbers! I feel much better now! I didn't think they would steer me in the wrong direction at Direct Tire but needed verification. Thank you!

I know the greatness of the Hankook , the unique Kevlar tread of the GY MTR and the sticky toughness of the Falken WP , but gimme the STT Discovery or the one pictured here and me and my Jeeps will be just fine; I have these on my XJ and STTs on my JKU and never would consider another tire. Nice Rock stuff images , dude . Also, nice tire choice ...

New to Jeeps and needing help.

I just bought a 2008 Jeep Unlimited with a small lift and 285/65 r18. It has the v6 and automatic transmission. The problem I am having is that I can't run overdrive and I am not sure if I am geared to high for the tires or if my engine is just running week. I wouldn't think it is engine since it only has 50,000 miles on it but I have only had it a couple of weeks and I am totally new to the jeep world. I did put the original tire size and the 285/65 r18 on a tire calculator and know that I am running 3 3/8 taller tires than original to the jeep.

Just wanted to give a big THANK YOU to all those who have contributed to this thread over the last couple of years! I'm a new JK owner and have been scouring the forum for the last couple of months for info about lifts, wheels, tires, backspacing, etc... This forum has been great, and what I've learned from all of you "experienced" jeepers has been excellent!!

I've just upgraded my tires/wheels, and wanted to share the pics for all those other newbies out there (like me) who are trying to envision what their ride will look like based on their tire/wheel choices (without any lift or leveling kit). I plan to add 2.5" - 3" suspension lift in the next couple of months. There is no rubbing with my current setup, but I don't intend to pursue any aggressive off-road action until the lift kit is installed.

Thanks again to everyone who has contributed!



2013 Jeep Wrangler JK
Suspension: stock
Wheels: 17x9 Level 8 ZX with 4.5" backspacing (-12 offset)

33's on stock 2011 Wrangler Sport Unlimited

Ok, I've read allot of mixed info out there on putting 33's on a stock Jeep. I've ordered TOYO's LT285/70R/17 A/T with Pro Comp's 7089-7873 17X8 wheels from 4 wheel parts and am supposed to get them installed Friday - from what I've read I may be better off going with 16" wheels with 285's for the spacing. Should I change my order?

No more stock tires and wheels!

[www.wranglerforum.com/images/dto_garage/users/202145/75609.jpg[/IMG]
These are 285 75R16 Falkens on 8.5" Level 8 Tracker wheels on my stock JK. No modifications needed so far, however, i haven't tried them off-road yet either.

Thank you! I love how it changed the overall appearance. The tires are on Level 8 Tracker 8.5" X 16 aluminum wheels. Other than the tires and wheels, the rest is stock.....for now.

So just so I get this straight. I have a '13 Jeep Wrangler 2dr with stock 225/75/16 and rims. According to this thread I should be able to mount Falken Rocky Mountain ATS (LT265/75R16E1 123Q W) onto the stock rims with no modifications thus no rubbing,etc? Is this correct? I can get 5 of the Falkens for just under $700 out the door incl mount,balance. I may do it tomorrow,havent talked to an actual person at Discount Tire to verify this will work , but I figure this board knows. Thanks

edit: And these are also 32in tires,correct?

I don't know the backspacing on the 16" jeep wheels, but if it's 6.25 like the 17s you should be ok. http://www.tirerack.com/tires/tirete....jsp?techid=53

Thanks for the great info on this thread.

Just wanted to double check with you all before I order.

I have a 13 Rubicon JKU. I am looking to run my stock wheels without spacers.

I have a 1 inch spacer lift and am not worried about the air dam (removed when installing LOD armor lite bumper).

I would like to purchase P 285/70/17 Duratracs.

Thoughts?

Are you gonna offroad at all? If so you'll probably rub. Mine did until wheel spacers were added, don't know if it was from the air damn but I don't think so. I have a 2" coil lift.

You could be fine though. You could always add washers to the steering stops but that would increase your turning radius. If you aren't offroading that won't matter.

Thank you. Yes I do go off road. I guess will have to go with spacers then. Any feedback/recommendations on them? It seems Spidertrax has a good reputation.

I have Spidertrax and have put them through decent trails no problem. Spacers do add an extra point of failure but I check the nuts when I rotate the tires. Haven't had an issue.

With the sway bars disconnected I still had fender rubbing so I chopped the stock fenders. This isn't necessary but I figured I'd lose a fender pretty soon if I didn't.

I already want 35s so I wouldn't go any smaller. They will work if you don't mind making a few minor adjustments.

Appreciate it. Looks like Spidertrax spacers it is.

I have a set of GoodYear Duratrac 275/70/18 and have ran across a stupid deal on a set of Mickey Thompson Classic II they are 18 x 9 13mm Offset and 5" of back spacing. Is 5" of BS too much our would this work?

Those should work for the current duratracs you have. A stock wheel with spacers is 4.75" and I run 285 mm tires just fine.

What is your current setup and what do you plan to do in the future?

something all should know there are a few wheels out there that are designed to fit perfect like a glove and designed to work as well. Interco tire co. Birddog wheel is made in a 17x9 with a 3.5" backspace ie. no spacers required to fit 37's or 35's for those that want a wider stance. might call it the perfect JK wheel. Discount tire, 4 wheel parts and a few others carry them or can get them.
the Birddog is also the strongest and lightest wheel on the market. stressed tested to 3000lbs with a 37" tall tire. suggest if your a real wheeler and not a boulevard cruiser, check it out. just google "birddog wheel" the facebook page is cool to.

I know this question has been asked many times, but want to double check before I order....

I'm planning on getting 285 75 16 duratracs or mt atz on a wheel with 4.5 or less backspacing. I have no intentions of getting a lift or leveling kit until my jeep is paid off. (5yrs) I notice most people that go with this tire size get a lift or level shortly after....
should I get a slightly shorter or skinnier tire, to stay functional off roads? or would slight fender flare trimming fix any issues?
appreciate any advice

I have that set up and if you go off road you will need to trim your flares or you will rub when flexed.

What is the largest Rubber Size (Tire) I can put on my stock 2013 (18") Rim? Anyone have any ideas? I would like to note that I am currently running with 1.5" Spacers.

The stock tire I believe is 255/70/18. I would like to go wider if possible....?

Thanks in advance!
