looking for a measurement

HI guys,

I purchased some wheels for my jeep and I would like to get some hub centric rings to help center them. Does anyone know the 02 wj hub size in millimeters?

Thanks
Erik

Thanks, that is just about what I determined. I measured the hub at 2.816 inches x 25.4 = 71.52mm.

Does anyone here use hubcentric rings for their aftermarket wheels? Just spoke with a guys at pro comp and they say not work worry about the rings because these wheels are lug-centric. I do no like the idea of centering my wheels based on lugs. Any input?

I have 30mm spacers on the rear of my Jeep which are aligned by the nuts (Not Hub centric) and the wheel fits over the Ring again centered by the nuts. I have no isues with any vibration or wobble. I'm running 265/65/17s

Whether they centre correctly or wobble or not is surely secondary. The job of the lugs is to hold the wheel tight to the mounting face....the job of the hub centre is to support the weight of the vehicle. You are making the lugs do something they where not designed to do.
If you are using lug centric wheels or spacers then the very least you should do is check the torque a bit more often than usual as every time you hit a big bump the force is trying to push the wheel sideways on the hub (with a rotary force) and this is what (given time) will try and work the lug nuts loose. This is why caravan are prone to loosing wheel in the UK because for some weird reason very few are built with hubcentric wheels and the owners dont seem to check the torques between services! (Im a caravan sales manager).
Even with my 1.5 inch hubcentric spacers , i check the torque on spacer and wheel nuts every 3000 miles (rotation time). Just my two pence worth.

Ok, just so we are on the same page here, I am referring to poly rings that are inserted into your aftermarket wheel and help center the new wheel over the hub. I will not be using wheel spacers. I do agree with checking the torque regularly on lugs. I also agree about the purpose of the hub and lugs.

I used hub centric rings on my lifted zj running 33s and that made mounting a snap as well as accurate. I do use a torque wrench with everything as well.

I want to know if anyone else thinks its important to center your wheel with these rings or just rely upon the lugs to center it. Comments are welcome.

^^What he said. Not the end of the world if you go with lug-centric, but I would avoid it.

The name of the ring you describe is a spigot ring

Everything I fit is fitted with the torque wrench. Which is then periodically checked.
