Hub Centric vs. Lug Centric Wheel Fitments

"What are these plastic (or metal) rings that came with my wheels?"

"Why didn't my wheels come with hub centric centering rings?"

The terms "hub centric" and "lug centric" describe the method used to center a wheel on a vehicle's hub to prevent vibration. Most Original Equipment wheels are built with the same centerbore diameter as the hub diameter on the vehicle so the wheel is centered as soon as it's sitting on the studs or the hub. Vehicles have many different hub diameters (or hub bores), therefore aftermarket wheel manufacturers generally make wheels with a large centerbore so the wheel will go on many types of applications. They either use a centering ring or conical seat lug hardware to center the wheel on the hub.

A centering ring (or hub centric ring) can be made of metal or plastic and either clicks into the back of the wheel or slides onto the hub of the vehicle - that way when you torque the lugs down, the wheel is already centered. The other way to do this, which is more prevalent on truck and SUV fitments, is to use lug holes with cone-shaped bottoms with conical seat lug hardware. When installing lug centric wheels, jack the axle up so the wheel and tire are off the ground, then firmly hand-tighten the lugs down so the wheel meets the hub. Then, gradually and evenly start applying torque a little bit at a time to each lug in a star-shape pattern. As you add torque, the cone-shaped lugs shift the wheel upwards on the hub and center the wheel properly, preventing wheel vibration.

I am missing one centering ring from my four 16 x 7.5 Mille Miglia Spider wheels purchased in May, 2002, order #5331946. Can I get a replacement centering ring?

Hello John,

I don't see that order in the system, but if you contact Customer Service at extension 4360 or email them at custsvc@tirerack.com then hopefully they can help you find the order and the information necessary to locate the centering rings you need!

I have heard you can't or shouldn't use hub centric rings on steel wheels. True? If so why?
Thanks

Hello Dave,

Correct, centering rings should not be used with steel wheels. Most of them are already hubcentric and the ones that aren't, such as the Black Rock steel truck wheels, they are lugcentric and still don't need centering rings.

I'm looking at some Ultra Motorsports wheels and I'm wondering if they come with centering rings? Specifically for 106mm hubs.

I ordered some aluminum hub centric adapters through tirerack and they came with 4 retainer clips... I don't know what to do with the retainers. I thought retainers were for wheel caps and not the adapter.

Sean, they might come with centering rings, but they may not. If they are necessary, we will include them with the wheels.

Ben, those are retaining clips for the aluminum rings. There should be a groove in the ring that the clip slides into.

I bought wheels for an 02 Lexus ES-300 to mount snows. I am trying to use them on my 15 Toyota Avalon and told I need centering rings. How do I determine what I need?

Hello Marc,

Your best bet is to take the wheels to an auto shop and have the mechanics there evaluate the fitment and determine what size, if any, centering rings you need.
