question about hubcentric rings

So i just got my FN five star 16x8 wheels (0 mm OS). Getting them installed next week. My tire place that I need to get hubcentric rings? we didnt check the wheel / hub specifically, he told me to get some before I bring the truck in. So my question do I need these and if so where do i get them? thanks

 

I thought that was a German car thing???

 

My 16" 5 stars went right on no problem! What the hell are hubcentric rings???

 

Your wheels didn't come with hub caps or a bag of plastic rings?

 

Are you sure that the FN wheels aren't hubcentric? My FN wheels for the 4Runner are. I would call him and ask. I had rings made for my JK from here https://www.motorsport-tech.com/contact.html

 

Most Toyota aftermarket wheel are already hub centric because they use the largest center bore. If you try and put a Toyota style wheel on GM, you need the rings

 

The only right answer is to call the vendor and ask. They should know the hub size of your vehicle and the centerbore of their wheel. If they are required they should have been part of the package.

Hubcentric rings are 'fillers' that are used when the centerbore of the wheel is larger than the diameter of the hub.

It helps keep the wheel assembly centered on the axle while mounting. It's especially needed if the lug are flat bottomed, not allowing the wheel to be centered on the studs via careful installation.

On my SoloII car I regularly mounted wheels that 'needed' hub rings w/o them, and never had an issue. But the wheels had tapered lug seats/lugs, allowing centering to occur by proper installation.

The tire shop is smart in asking for this bit, just to make sure the customer doesn't show up w/o all the right parts and frustrate the customer and waste an appointment slot for the shop.

 

FN is all hubcentric. Konig models specifically designed for Toyota trucks and SUV.

 

thanks, I will call dustin at FN on Monday, i think the bore is 106mm same has the hub so i wont need the rings

 

question for ya'll.....I am getting some wheels today and the hub size on them is 106.25mm and our trucks are size 106.1mm......will I need any hub rings? or will I be okay without them? I mean it's .24mm difference. If I do, what size ring do I need?

 

No such thing as quarter millimeter thick ring for wheels. That's shim thickness territory.
