Contour Enthusiasts Group Archives Forums Modifications Wheels & Tires Centric rings??

I called two belle tires, one of them in Flint Mi and the other in Burton Mi.

It's a lie that they're unnecessary or a lie that they carry zero weight of the car? (Actually they're both true statements)

weargle is right but wrong at the same time. the rings are made to help even torquing of the wheel, this is true. however, without them, the idea that the wheel went on a little bit not cenetered certainly isn't unheard of. i'd get the rings and see if it doesn't fix it. they're not much money even if it doesn't, and it certainly doesn't hurt to have them. i'm a belle tire employee also. 63.36mm hub size is the size you'll need

How much approx for the set??

no idea off hand. something like $12 if that. i dont know why that price is stuck in my mind, but it could easily be cheaper. call any belle tire and ask, all of them should have that size...its fairly common.

i'm from store 33

Hubcentric rings as the name implies, centers the wheel onto the hub. Lug nuts alone cannot do this sufficiently enough to remove the out of alignment inherent when you try to line up a big hole over a slightly smaller shaft (i.e. the wheel hub bore over the hub mounting ring).

Once the rings align the wheel centrally to the hub the FRICTION between the wheel face and the hub face is what actually carries the weight of the vehicle, NOT the rings and NOT the studs either.

The point of ths post is that without the rings you will NEVER be able to align the wheel to the hub properly and you will get virbration, not matter how perfect the wheel and tire balancing may be.

End of story.

With flat lugnuts maybe not, but with any taper in the seating there will be no problem whatsoever. Or I'll let you drive my Miata that has never had hubcentric rings on the ATS Comp Lites (or on the Contour either for that matter) and let you try and find a shimmy up through 100mph.

You're wrong. Bolts, tapered or not are NOT sufficient for wheel centering. That's why in engineering design we use bore pilots on components that need to be aligned raidally!

Have you even checked to see if the bore of the wheels you have possibly is already the correct size, thus eliminating the need for rings? I bet when you're wheel is put onto the hub there is litle to no radial play in the interface thus you're set. But in the rest of the cases, wheel manufacturers will make the bore of their aftermarket wheels the largest size to suit the largest hub size of the vehicle that same bolt pattern, and then use hubcentric rings to resize the wheels to suit all the cars with consequently samller hub diameters.

your a super genius.
