We frequently see questions regarding hub centric rings so we decided to put this thread together to help answer some of these questions.

First, some terms you will need to know.

  • “Hub Centric Wheels”

Hub centric wheels have a center bore that matches the vehicle’s hub pilot.

  • “Non Hub Centric Wheels”

Non hub centric wheels have a larger center bore than the vehicles hub pilot.

What are hub centric rings?​

Hub centric rings, typically made of plastic or metal, are designed and used to fill the gap between the hub pilot of the vehicle and the
center bore of the wheel.

Here's what the hub pilot, the center bore of a wheel, and hub centric rings look like:





What purpose do hub centric rings serve?

A hub centric ring’s sole purpose is to help align and center the wheel and tire assembly on the vehicle’s hub pilot. Once the wheel assembly
is torqued, the hub centric ring’s job is complete. Hub rings help reduce and can eliminate wheel and tire vibrations caused during installation.

Do all wheels need hub centric rings?

No, not all wheels need hub centric rings.

Wheels that are “Hub Centric” for the vehicle will fit over the vehicles hub pilot without any gap. All original equipment and some aftermarket
wheels are hub centric but most aftermarket wheels are not hub centric.

Wheels that are "Non Hubcentric" can be mounted without hub rings if the proper time and care it taken to center the wheel on the vehicles
hub during installation.

I read that you have to run hub centric rings on non hub centric wheels or the lug nuts/studs will break do to extra load. Is this
true?

This is not the case. The vehicles hub pilot, studs, and lug nuts are not load bearing. What actually holds a wheel on the vehicle is force friction
that is created once the lug nuts are torqued to specifications set by the vehicle manufacturer.

How are hub centric rings sized?

Hub centric rings are sized by the outer diameter to inner diameter. The outer diameter is the hub bore of the wheel and the inner
diameter is the hub pilot on the vehicle.


Here's an example:

The hub pilot on a 2000 Nissan Altima is 66.1mm. The hub bore on the 17x7 Konig Unknown (a popular wheel for this application) is 73.1mm.
From looking at the hub pilot and hub bore specs, we know there is a 7mm. gap. To fill this gap a hub centric ring is used. The correct ring
size for this particular application is 73.1(Outer Diameter) to 66.1(Inner Diameter).


Which material is better, aluminum or plastic?

There is a lot of debate on which material is best and there are Pros and Cons to both. Here's our take on the subject.

If you live in an area where snow and road salt is present, or in an area around the ocean, plastic rings are best used. Unlike the metal
aluminum rings, the plastic rings will not oxidize and corrode.

If you push your vehicle to the limits and are constantly on the brakes, like when road racing for example, a metal hub centric ring is best
used. Contrary to what you may read, under heavy braking or racing situations, plastic rings can deteriorate from the heat being
generated. The heat can break down the plastic material making it brittle which can ultimately lead to the ring braking. Although rare
and under extreme conditions, the plastic ring can completely melt and deform.

If your vehicle is mainly used as a daily driver, pick one and go with it, either one will get the job done.

Discount Tire Direct includes hub centric rings FREE of charge (when applicable) with every set of wheels we sell. We also sell hub
centric ring sets in both plastic and aluminum for only $15.00. This price does include FREE shipping so if you need a set of hub centric
rings, give us a call at 1.888.459.4080 and anyone of our agents would be happy to set you up.

BTW - if it's confusing, "non-hub-centering" wheels are also called "bolt-centering" or "stud-centering" The function still exists, it's just handled at the bolt circle. This is a design decision for the *vehicle*, not the wheels; the wheels just have to match.

KeS

And yes, I've melted plastic centering rings to my hubs in my autocross car, and yes, they're a PITA to chip off. Don't think it would normally be a problem on a Ridgeline, though.

does that price of $15 for the rings apply to local store sales. im in orlando also i bought a set of 06 bmw x5 wheels 17x7.5 do i need a 64.1 /74.1 TIA for any answers
The Honda is 64.1mm and the BMW wheels are 72.56mm, my invoice says GORILLA HUB RING SET, product code: 81901. The rings I got today are Aluminum and stamped on them is HCR07M-4. Have not had time to make sure they fit, will do tomorow. Just get em online and they ship em free to your house. For 15$ its a screaming deal! My local tire shop wanted 60$ for a set.

i just order rings for the same set up and i gave part number and the sizes and they said the closest one they have is 72.6mm not 72.56. but when you look at the x5 specs the wheel hubs say 72.5
i hope they fit. order same part number but in plastic 81901
also the plastic rings were 5$ but the metals were 20$
and theres an extra 30$ for boarder fees so they say

Here's a question for an expert....
Are original 2010 17inch AWD Touring Pilot wheels 'hub centric' if I put them on my 2018 Ridgeline? Or, do I have to use the hub centric rings?
Thank you for reaching out, efeinblatt.

Both vehicles utilize a 64.1mm hub pilot so the fitment is hub centric and you would not need hub centric rings.

On a side note, I suggest test fitting a wheel on the front axle if possible before purchasing to ensure there is adequate brake caliper clearance.

Maybe you're reading my mind :). I want to fit a 245/70/17 (Nitto Terra Grappler G2) tire on the Ridgeline, so I'm going to have to buy new wheels (and tires). I figured the Pilot wheels might work and be hub centric at the same time. I assume you're asking me to check the brake caliber clearance because of the larger tire size, right? Not because of the wheels themselves, or am I missing something? I'm trying to emulate what JSPORT does with their packages without paying through the nose to go through their dealer network. Or maybe I'm just being stupid .... I know you carry these tires and wheels to match ..... maybe you can make a recommendation....

Hi, efeinblatt

Caliper clearance is the distance from the spoke of the wheel (back side) to the brake package. We do not have O.E. wheel measurements for this so while the wheel may appear to fit from a width, offset, center bore, etc standpoint, the wheel may rub on the brakes. This is why I recommend a test fit if possible.

As far as aftermarket goes, we offer a wide selection of 17-inch wheels for your Ridge and while not hub centric, hub centric rings are included for no additional cost :cool:

If we can help put a package together with you, please let us know! Also, feel free to check out the selection our mail order arm, Discount Tire Direct, offers. Shipping through DTD is FREE and they mount and road force balance all tire and wheel combinations for no additional charge!

Thanks Discount Tire. I have actually spoken with your people by phone earlier in the week and will be buying my tires from you! The support your company has given this group has made me a believer!

Regarding the caliper clearance .... I did a quick search in the forum and read that several people had successfully put the Touring wheels on their 1st Gen Ridgeline. So, does that mean it should work for the 2nd Gen????? Don't really know the difference in the wheel well.

That's awesome to hear - thank you for the kind words and the opportunity at your business!

I don't recall seeing the Touring wheels on a 2nd gen so I can't tell you one way or the other if they'll clear the brakes. The other dimensions such as hub pilot, width, offset and lug holes are good to go, though :cool:
