Whats my wheel bolt pattern & lug nut size?
 
You may find this chart from 4-Wheel Parts useful:
http://www.4wheelparts.com/downloads...lt_pattern.pdf

Lug nuts:
All 6-lug full size Jeeps = 7/16-RH
All 5-lug Jeeps after 1969 = 1/2-RH

Prior to 1970:
All Willys and Kaiser Frasier MA through CJ5, truck, and trailer models had left handed lugs on the left side from 1941 up to 1969
For more info see Post #18: http://www.jeepforum.com/forum/f15/w...l#post10341903

Bolt Patterns:
5 on 4.5in (5 X 114.3mm):
Wrangler TJ/LJ
Cherokee XJ
Commanche MJ
Wrangler YJ
Grand Cherokee ZJ
Liberty KJ

5 on 5.5in (5 X 139.7mm):
Jeep CJ

5 on 5in (5 x 127.0):
Wrangler JK & Unlimited
Grand Cherokee WJ & WK
Commander XK

6 on 5.5in (6 X 139.7mm):
Full size Cherokee & Grand Wagon

FAQ: Will a 5 on 5 fit on a 5 on 4.5?
In other words, Will JK wheels fit on my TJ?
Answer: NO. You need wheel adapters.

Spidertrax sells them:

I'm having an issue cause I and trying to put a set of American Racing Wheels (5x4.5) on my CJ7 (5x5.5). I was looking at the adapters, which seem like a great idea, but now I'm getting cold feet cause I don't think the wheel hub will fit over my locking hub on my CJ. Can anyone help me on this?

Here is a useful write up on hub centric vs lug centric in wheel spacers:

yup, because they use acorn style lug nuts. hub centric simply means there is a detail on the hub to center the wheel, so when you slap the wheel on its not resting on the lug nuts alone. it rests on the axle detail that sticks out, or in the case of spacers, it rests on the hub centric portion of the wheel spacer. this is an advantage when you're changing tires because you set the tire on the hub and walk away and the weight of the tire isn't sitting on 2 or 3 threads of one or two lug nuts. this way, when you tighten down your lug nuts, the lug nuts don't have to push the weight of the tire up to center the wheel. hub centric isnt necessary, but it sure makes life a little bit easier.

see that shelf in the center of the hub your wheel rests on when lug nuts are NOT tightened??

Wheel spacers that are NOT hub centric don't have this detail:

But hub centric wheel spacers do:

Look at the backside of a pair of Spidertrax wheel spacers, they're actually machined to have the same details as the backside of stock Jeep alloy wheels.

Just to keep the information flowing and to answer another FAQ... If YJ wheels are lug centric then why does the hub size matter? In other words, why can't you put a JK or CJ wheel on a YJ or TJ?

Hub centric and lug centric have nothing to do with the bolt pattern size. see above that the measurement between the wheel studs it different. that is why a jk or cj wheel wont fit on a yj or tj with out an adapter.

and a note for the older post. No one makes an adapter to use a 5 on 4.5 rim on a 5 on 5.5 axle because the hub is too big to fit the center hole of the rim

Its also worth noting most aftermarket wheels have a different center bore than stock wheels. This means aftermarket wheels are no longer hub centric - and the lug nuts are forced to push the weight of the wheel+tire around to center it. If you're not careful, you could easily torque your wheels down off-center. I hold my aftermarket steel wheel/tire combo up with my knees, hand tighten the lug nuts, then use a lug wrench to squeeze them down, then finally a torque wrench to tighten. I then recheck the torque once the Jeep is on the ground.

What is a good place to shop for black wheels that are going to fit on a 2007 Jeep Liberty Sport? I'm having a hard time understanding which size is for my Jeep. I've also read that the front and back wheels on my Jeep are a different size? Anyways, if I could get a general tutorial on my Jeep's specs that would be greatly appreciated!

Size
 
I went to Autozone to pick up some new chrome lug nuts, 1/2-20", but they will not screw on. Should it be another size? I see on the top of this post that it should be 1/2-RH, but that the same. I have a 1984 Jeep CJ7 Laredo.

Backspacing
 
Unlimited04,

The only thing that I can think of that would be helpful in your list would be the standard backspacing for each one. I'm looking to get a set aftermarket wheels and can't find what my backspacing is. I have a 04 Rubicon.

no way i can list the backspacing for every wheel every vehicle chryslers has ever made. check each individual tech forums for that info.

Rubicon wheels are 5" backspacing. You need to space your wheels out more with less backspacing if you want to run bigger tires, otherwise they end up rubbing on suspension components.

should be, but i may have an error, I don't know much about CJ's. are the threads clean & not rusted? are the diameter's different?

As for FYI & FAQ regarding backspacing...

Would the correct 5" backspacing on 16" Moab wheels also be the correct backspacing with 16 x 8 steel wheels? (especially if maintaining stock 31" tires)?

16x8 steel wheels weigh like 50+% more than your alloy Moab's....not cool. No sense in adding 100lbs to the rotational mass of your drivetrain.:confused::confused:

If you're just running 31s, buy whatever style wheel you want. Buy the backspacing & wheel combo which you like. Go wider than stock with less backspacing, or the same as stock, just don't go inboard with more backspacing. Buy wider flares if you need more tire coverage.

I'm tired of dealing with corrosion on these (and others in the past) cheap cast aluminum Jeep wheels. As much as I like the appearance of my stock Moabs (Yes I own a Rubicon), I'm thinking steel is the way to go. Mind you I live in the heart of the salt-belt (Chicago) and I don't want issues with wheels leaking air (especially) during the winter. It irks me that I'm dealing with this again (2nd time this year) during 80 degree weather. My local Discount Tire shop tried to clean-up two of my Moabs earlier this summer -- and they're leaking again.

So I will assume 5" bs on steel wheels (decided on Black Rock Wheels) will work. I may go up to 33's sometime before next spring but for now I am sticking with my 31" stock GY MTR's.

- Thanks.
