How tight should hubcentric rings be?

Default How tight should hubcentric rings be?

I recently ordered some 17" rims and tires (Konig/Kumho) from Whalen Tire. When I went to install the hubcentric rings, I had to tap them in the back of the wheel with a rubber mallet. They fit snug, but it seemed like a good fit. Then when I tried to mount the wheel, I kept rolling it around trying to get it to seat on the hub and it wouldn't. I tried a different ring, and the same deal. I even tried pounding the wheel with the rubber mallet to see if I could get it on a bit. No luck. Oh the rings said 61.7mm on them if that means anything.

Seeing as I've never used hubcentric rings before, is this normal? I can't see how... Any ideas? Thanks.

Mine were a pain in the a$$ to put on, since they were so tight. I don't know for sure how tight they are supposed to be, but thinking about it, it makes sense for them to be tight, after all their job is to hold the wheel onto the hub.

tiby hubs are 67.06mm or 2.640"

Hubcentric rings that are 61.7mm will never fit on there. They sent you the wrong adapters.

they should be pretty dang tight. they're the last thing that makes sure the wheel's dead center on the rotor. i just put mine on in the wheel, then mounted the wheel, when i torqued the lugs on, it snugged into place (it really didn't have a choice).

Oops, I misread them. They are 67.1mm. So I guess they are as close as they are going to get? I'm not sure what kind of intervals they make these things in. I never thought of just screwing the lug nuts on and letting them do the work. I will try that.

If the hubcentric rings are plastic, you will probably crack/break them by doing that (hubs in wheel, bolting down lugs).

Put the adapter on the HUB first. Then mount the wheel to the hubadapter, then bolt on the lugs.

Also, clean all the rust/dirt/corrosion from around the hub, lube the hub with motor oil, lube the inside and outside of the adapter with motor oil, and lube the inside of the wheel hub with motor oil. That should allow it all to fit on nice and easy.

Oh..one last thing. Did you remove the 2 screws in the rotors? Those will prevent most aftermarket wheels from sitting flush. Remove the screws or counter sink them and replace the stock screws with countersunk screws. They are not needed so you can just remove them.

I did remove the screws. I stripped one out pretty badly and had to use a vise grips to remove it.

I did try putting it on the hub, but it still wouldn't go on easily. I'll try lubing it up. If the specs are right, there is a .04mm difference, which should be OK, I hope. Thanks!

I got my rims, Enkei CDR9s, from Whalen Tire also. The rings they sent me were a snug fit as well. Like Random said, be sure to clean the rust, dirt etc. from the hub. Be sure to get all the rust off. I tapped mine on with a mallot in a zigzag pattern, to make sure they go on evenly. (i.e. 12 o'clock, 6, 9, 3, 12, etc. They will be very snug. I had to buy new ones for this year b/c in order to take them off, you end up ruining them to put stockies back on for the winter. Oh yeah, once they get flush, you still have to push them back a bit. I did this by using a flat head screwdriver and applying pressure gently in the zigzag pattern. Hope this helps

Well the first time I put one on the hub, I was able to get it off again. But well see if that's stil true come next winter. Anyway, I got them on, Random's advice worked. I had to torque them on though, they didn't want to fit on without "motivation". Even painted the calipers while i was at it. Thanks for all the advice guys, I just didn't want to screw it up wink
