HUB CENTRIC VS. Lug centric rims

[DW-kqtv]

This information, as with many other videos on this subject, is incorrect. The lugs do not ever support the weight of the vehicle. Even in a so called "Hub-centric" case, the hub center does not support the weight of the vehicle. When the lugs are tightened, the clamping force caused by tension on the lug studs creates a friction force between the mating faces of the wheel and hub. This friction force is what supports the weight of the vehicle. Unless the lug nuts do not have conical or radiused faces the lugs will center the wheel on the hub. If "hub-centric" features are added to the assembly then that fit will be in competition with the centering provided by the lugs. In some cases the hub center will influence, but not fully determine, centering, and in others there will still be clearance all around the hub center. Which occurs will depend upon the manufacturing variation of the particular hub and wheel combination. Unless the wheels are press-fit on the hub centers (an they're definitely not), there is always some clearance between the hub center and the center bore of the wheel, even with "hub-centric" fit. There is never "perfect" fit of anything. Hub-centric fit will tend to help when proper lug tightening procedures are not followed, or for a case in which the wheel or the hub has a slightly off-centered lug pattern. Hub-centric fit will not help at all if the particular wheel happens to have an off-centered center hole. All this talk about how hub-centric fit and rings are important is based on conjecture and opinion, rather than on engineering principles and facts. They may help with a centering issue in some small number of cases, but they're generally only an assembly aid.

First off, great video but you are incorrect on what carries the weight of the vehicle. Weight is not carried by the hub or the lugs. It is carried by the friction between wheel and hub due to the lugs being tightened. I know people are going to be disagree with this but it just takes a little common sense and thought. When you tighten a wheel to a hub, think about contact points. Of course you have the wheel against the hub but the studs themselves are centered in their lug holes. The wheel is not resting on the studs. You have contact points between the studs and the wheels through the lug nuts. But this contact isnt carrying weight. Rather it is creating horizontal pressure (friction) between the wheel and the hub.

The wheel is attached to the hub by the conic lug nuts and yes, the hub is only there for centering. You won't need rings if you installed and torqued them properly.I totally agree with the previous post

If the weight of the vehicle was on the hub of the rim you would see wear musgroming out the center hub. You don't see this because the weight is locked in to the axle by the lug nuts not the center hole.

Been using lug centric wheels for all my vehicles Winter tires for years.
No problems, very simple.
Nothing to see here folks.

Thanks for this video, it's very helpful. I got some steel wheels on my new car and feel a thumping when going around turns, and I think this is the problem. Fortunately, the shop is going to take the steelies back and replace them with correct hub centric alloys.

That was a great description thank you for making it easily understandable. I watched about 3 TikTok’s before I saw this trying to figure out what hub and lug centric is and I couldn’t understand anything they were saying until I saw this video. It was like I work there with him how well I understood that.

It kind of blows my mind that some ceo was listening to some person pitch them the idea of lug centric wheels and actually thought: “ oh wow, instead of the support of every single lug nut AND the entire drivetrain of the car, let’s ONLY use the lug nuts !!😀”

Hi, just want to mention something I have argued over with tire shops balancing my lug centered rims. Hub centered rims are center hole spin balanced, using the cone centering method. My lug centered rims require the plate that is attached to the rim with the lug nuts, then the plate is mounted to the machine with the plate's center hole being true center to the lugs, because the rim's center is NOT true center. If they balance a lug centered rim without the plate by using the cone (as they have with many many rims), the rim is not balanced to the lugs, and this may look and feel ok on that machine, but it rides like it's out of balance driving down the interstate. Cause it is still out of balance. Be sure they know your balancing requirements. Look at the plate they want to use. Is it a finger plate pressing the rim tightly against the cone or does it bolt to the rim? And you might have to teach them something about proper lug centered balancing. Good Luck on the next re-balance.

Yes and no
Hub-centric= Stuck buying brand new. Bcoz the specs are to hard to find.
Lug-centric= Used rusty rims are Cheap!!! If the weight of the car was carried on the tiny lip of your hub you would have big problems; it's just 3/16" Hammer 500lb on that (2 ton car/4 tires).

Thanks for that great explanation. This is important information especially this time of year whe people are putting on snow tires.

[nghiadinh]

Great simple video. I was asked this question and this video answered it all!🤟

[OGkol]

For lack of a better word... THANK YOU! Very much!

I disagree on this for this type of wheels with conic wholes. Wheel should be lug centered not hub centered. If the fit on hub is too tight you never know if the lugs will be equally in place due to the cones proper sitting around lug. It is actually those very cones on the wheel wholes that should center wheel and no, nor hub nor lugs carry weight it is friction between wheel and rotor. If you do not have wheels with conic wholes (typical with alloy wheels) and your wheel center is wider than hub you need proper hub centric conic rings.

Thanks for the video, but I've seen were lug centric wheels wont balance correctly Is the hole off center than why would centric rings help?

Hi, I have purchased steel after market rims with larger bore diameter. Can I buy hub rings to make them hub centric? Do you know if these rings will fir steel rims or not?

[moreeshintaro]

Hi there I just installed winter tires on steel rims for my 2015 accord which bore is 64.1 and found out the steel rims were for camry 60.1 bore size. Once I installed it's not sitting on the bore hub kinda sitting flush. I've driven the car to mtl and back no vibrations or anything. Should I be worried? Both bores are centered just doesnt sit.Thanks

[giorgosnak]

If the rings are custom made is it better to make them by steel for more strength (or stainless steel) than aluminium?

[MRMAN-wbtv]

*THEIR ARE SOME COMPLETE IDIOTS ON THIS POST SPEWING THE SAME INSANE RHETORIC!!! The video clearly shows that if your rim isn't hub centric it will cause play, you think bolts will keep a wheel centric at high

[sDurango]

Something different there ?? I just bought OEM Hub Centric rims for my 2004 Hyundai Accent, , it has a 4 x 100 bolt pattern with a 54.1mm Center bore ...
