Lug-Centric vs. Hub-Centric

[JD Larue]

Yeah to me it sounds like a horrible idea, I remember you from TF!?

Yeah, that was me. I just found out about this forum and came on over.

all the ring does is center the wheel better than utilizing the lugs to center the wheel before cranking them down tight. I have lugcentric on both my H3 and Tahoe. Without the rings, the vibrations sucked! After the plastic hubcentric rings were installed, the issue went away almost 100%.

If you have a choice, go with hub centric, but if not, just make sure to use the rings. plastic or aluminum they do the same thing, the aluminum would be my preference, but I have plastic on both trucks. I have about 13K on the H3 with 35's and no issues. The Tahoe only has about 1200 miles with these 17" Hoss rims, and 285 bfg at's.

It has to do with the way the wheel seats on the mounting surface. Take a look at a toyota wheel next time you see one, even though the bolt pattern is the same as a gm 1/2 ton, the hub bore is significantly larger. Toyotas use a lug centric wheel which requires a shank style lug nut that sleeves into the lug opening in the wheel whereas the gms are seated by the hub bearing assembly. You can use toyota wheels on a gm, just be sure to use a hubcentric ring, effectively taking the place of material otherwise present in a hubcentric wheel design. I have lots of rings floating around my shop if you need a set.

Thanks Max, I should be picking up a set from you in the next months as you know the size I need!
I just looked at a Sequoia wheel and noticed what you are talking about!

OK, that sounds like something I'm running into.

I have some lug-centric wheels mounted on my '01, and can't seem to shake the vibration. (wheels mount with acorn style lugnuts).
How do I go about getting a set of adapters? How does the sizing work?

i have no idea if my rims are lug or hub - centric? how can i tell? any pics?

 

[Modded]

Uhm, the best I can say id to pop the center cap and see if its touching the hub (circular metal peice immediately behind the wheel) dead in the middle, if not then its held up by lugs and is therefore lug-centric!

Does anyone know the Hub size for '02 yukon 4wd? I think this is my problem with the 20" ASA wheels I have, I believe the wheel center bore is 108mm
