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.

Spidertrax spacers:


Jeep Ravine wheels:


After learning the subtle differences from one of the co-owners of Spidertrax about , I decided to buy their product.

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.
