k2enemy You put the wheel on the ground face down. Then place a straight edge across the diameter of the rear of the wheel (not on top of the lip). Then use a ruler to measure the inches between your straight edge and the mounting face of the wheel. Voila, your back spacing.

Cordite I am equally as slow at the above poster. Can any one tell me what is the width of the stock JKU 16 inch steel rim. I know the tires are the P225 size and that they are 29 x9 but does that mean the rims are 7.5, 8 or 8.5 inches wide? I can't afford the new wheels now but want to put some decent size tires on. I'm going to put a 32 inch tire on but want to go to 10 or 10.5 inches wide without needing spacers or stops or having any rubbing. It's a DD with some trail use.

Any help is appreciated.

TBritt93 I'm feeling a little slow, but could anybody explain how I measure or figure out said backspacing? Looking to get the Metalclock 3.5" Arb edition lift and one required field ask do you have more or less than 5.5' of backspacing. Thanks for any help offered.

brunetpi Ok, I have read all 5 pages of this thread and I am still confused.
I have a 2006 LJ, 4" Skyjacker Value Flex Lift, stock rims, BFG 33x12.50R15LT, Mud-Terrain T/A KM2's, and 6" Bushwhacker fender flares. The Wheels are rubbing really bad, haven't dared to take it any where to say the least. I am looking at getting Pro Comp Series 51, 15x8 with 5 on 4.5 Bolt Pattern with Backspace: 3.75. Is this the right move?

mouse1 3.5" backspace on a 15x8 wheel running 31" bfg at stuck the wheel out big time. I put the rim onto the hub and the rim was so far out. I am bummed. So now its going to cost me to ship these things back. The wheel guy said they would look great.

1994 YJ I have a 94 YJ with 4" rough country and 2" shackle. can i fit 35x12.5's? if so do i need wheel spacers??
02-19-2014 12:03 PM
Maine Jeeper Is there a big difference between steel rims and alloy or aluminum? I am in the process of upgrading from 33x12.5x15's to 16". It seems all the rims with any type of design are alloy and steel are pretty plain. I want something "tough" looking but also durable.

BlOwNXT New here with a question. I have an 05 TJ with a 3 inch Rough Country suspension lift. I am looking at getting pro comp wheels that are 15x8 with a 3.75 back spacing, and 33x12.50x15 tires. Am I going to have any rubbing issues, and is the is a common setup to run?
10-12-2013 11:48 AM
drtire there is one wheel out there that is designed to fit tj's, yj's and Cherokees perfect. its the Interco Birddog wheel. 15 or 16 by 9 with a 4.5" backspace. 31/1050r15, 32/1150r15 or even 33/1250's fit perfect not too far out but just enough clearance to clear the sway bars on control arms. on top of that the are designed to work. even have two valvestems. you will have to go to the Interco tire website and click on the wheel to see all the features. it was not designed as a looks only wheel.
someone else suggest the Interco Trxus MT tire, great suggestion on of my favorite tires in the industry.
hope that helps. discount tire, 4wheeler parts wholesale and others can get you fixed up.

k2enemy I'm looking at a 4.25" Zone lift and 33x12.5x15 Duratracs on 15" steel wheels. The Zone lift calls for 3.5" of BS. My buddy has a set of d-window wheels which have 4" of BS for next to nothing. Is this going to become an issue or can I simply adjust my steering stops? Thanks.

stzd8 I apologize for 'another those questions' type but I am about to order the Dick Cepek Toque Gun Metal or Black on 17". I currently run an AEV 2.5 lift kit and plan on replacing the tires to a 285/70/17 ones.

Will I have any trouble running them without spacers?

07-26-2013 03:35 PM
gyramax I'm looking at a set of Pro Comp Rock Crawler wheels for my 2006 LJ. 15 x 8 with 4.5 bolt pattern. My question is about backspacing. They come in 3.75 or 4.50 BS. Which would you recommend if I want to run 32's or 33's?
07-01-2013 07:17 PM
New to jeeps, so confused

Really need some advice if you guys could help me out..
I have an 06 wrangler with stock rims and tires. Right now I know I want 18x9" wheels with 33" tires. I know first off I will need like a 3" lift. My main questions are what backspacing/offset is needed and what tire width should I get? With that being said, I want to get fender flares that line up with the tires, and those will either be 4.5" or 6". You can probably tell I don't offroad really, I just want this to look good. If you could tell what's the right combination to get that would be awesome. Any adivice would be appreciated!!

That should be a bingo. My tj came with 15x8 ecco which is a 5.5 bs , +25mm offset.
I had 225/75/15 tires. This is about 9.5 wide and 28.5 high. I wanted to stay 15x8 in a custom wheel but could not find a 15 wheel that did not have a 3.5 bs, -27mm offset sending my wheels out 2 inches + another inch for the bigger tire. Very popular look in GA. I could have gone all black as there are a lot more choices in bs. Instead,I went ions in a 16x8 with a 4.25 bs, -5 offset to get to a 265/70/16. Bigger look with no lift no rub. Cooper Discovery A3s. So instead of sticking out 3", I am at about 2.25. Not much different but the 16s look good. did wheels and tires for about 250 each. PS tire dealer was great. mounted one up (therefore I could not return rim) to check everything out.
I have a 45 MB military so this is my first tj. I did all my research off my stock tires bs , width, height, and used the offset as a quick check. If you look at a lot of custom wheels you will find I think a lot of 3.5 bs which really frog out a 15 x 8 in a bigger tire. Oh well, first timer logic. not a rocker or a mudder, mostly road and trail. My apologies up front to all tjers.

locker20 I have a 10 Saraha Unltd. Had (still has) 255/70/18's on OEM wheels. I bought Wild Peaks 325/60/18's and was told they would work with 1 1/2 spacers. well.... the tires wont go on the wheels. now I'm looking for wheels. I'm looking for something like the KD Hoss, Rockstar or Addict wheels. my current backspace is 6.25" + - . Am I correct that if I purchase wheels with a 4 1/2" BS that I will not need the spacers? I'm looking for ideas/suggestions. (picts would be good also) It looks like this is not a common mix (18" with 4 1/2 BS). tks for any input!!
05-27-2013 07:05 PM
t84a Ok. I have a 2000 Wrangler Sport. My tires are P225/75R15 102T. I have the stock alloy wheels but they're all pitted and scratched. I actually like the passenger tires. They are the Radial Long Trail A/T. I'm looking for a good looking wheel and will probably just put the exact same tire on. What would that translate to backspacing? Thanks
05-06-2013 07:32 AM
shrwud96 I have stock wheels, with no lift "YET" on my '08 2 dr and have 285's and they look good. Not sure what OEM backspacing is off the top of my head, but there is 2" wheel spacers and this puts the stance right at the edge of fender flares (stock also). Hope this helps.
05-03-2013 08:37 PM
pmyers I have a 2008 JK with oem 17's on it. Its time for new tires and I want a wider stance. With no lift I'm gonna stay with a 265 tire. Anyone know what offset in a rim I would roughly need to get my tires an inch and a half or so out from the edge of the factory fender guards?

17x9 raceline Raptor on 2013 unlimited offset???

Hi All,

I am looking at buying 17x9 raceline Raptor wheels for my 2013 jeep unlimited. They are telling me they are either Zero offset or 5.0 inch backspacing. Everything I read is I shouldn't have more that 4.5 backspacing or -12 offset. I'm looking at putting these wheels with 285 70r 17. I'm nervous about ordering these. I'm new to this and I really appreciate any knowledge.

03-21-2013 08:30 PM
17" Rims

The real reason is the price of the rim from a friend are real cheep. But with a big off-set I'm concerned about the inside rubbing. Will that web site help there too?

Thanks for the help.

17" rims from Jeep Cherokee

Another dumb question from a new/old jeep wrangler owner. Can I put the 17" rims from a cherokee on my wrangler? Looks like the offset discussed earlier may be an issue?
03-08-2013 12:23 PM
jasper7 I am planning on buying the Teraflex 2.5" with bilstein 5100's which requires a 4.5" bs or less.
The wheel I want is Fuel Throttle 18x10 with offset -12. And I want to wrap it in Toyo MT 33/12.5/18.
now i think that allthis will play nice together but my question is about the bs. will that work and will the tires extend out past the fenders and if so how much? Im an idiot when it comes to the offset/backspacing thing.

Anythoughts and or advice on this particular set up would be awesome!
03-04-2013 10:27 AM
lee indy those will work. its 4 in BS. get em.
03-04-2013 10:25 AM
mscofer The wheel I want only goes down to a 17". This is a mall crawler. Thanks for the link. I may just go with the DC-2 instead.
03-04-2013 09:33 AM
lee indy Custom rims, wheel tire packages for your ride -
use that link to see what it will change exactly

that being said on a tj and even a jk why are you going to a 17? compare rubber prices 15-17 rims. not to mention with a smaller rim you get much more side wall to flex and then the extra weight of the rim will make you loose more performance.

9" wheels

Can you put a 9" wheel on a stock tj. The wheel I want is a 17x9 with a -12 mm offset. I was wanting to go with 265/75/17 tires. A tire website says it won't work because rim is too wide and offset it out a reccomended specs. Is there a solution??

02-25-2013 04:51 PM
Tadstj83 I just bought my 97 Tj and its all stock . I ordered a lift, 33x12.50 tires,but haven't ordered the wheels. What back spacing do I need on 15x8 wheels?
02-21-2013 01:11 PM
elclipo I'm on the other end of the spectrum here. I have 33x12.50x15 tires on 12.50x15 wheels, no idea on the backspacing. I like the 12.50 tires but I am concerned about the wheels being so wide both for the sake of the hub and ball joints as well as the wheel itself since it sticks out so far. Also as I learned in this thread, airing down could be an issue as well.

To keep the same size tires, should I get 15x8 wheels? Any real advantage/disadvantage to keeping the current wheels?
