Xxyyzz Posted November 13, 2012 Share Posted November 13, 2012 The guys who balance my wheels say that I need to buy hub centric rings. Can anyone direct me to a proper size? These are the wheels I have: http://www.summitracing.com/parts/crr-3425834/overview/ Thanks, Mark Quote Link to comment Share on other sites More sharing options...

wallaby Posted November 13, 2012 Share Posted November 13, 2012 That's weird: right on the info page it says "hub centric--NO". Quote Link to comment Share on other sites More sharing options...
monte70car Posted November 13, 2012 Share Posted November 13, 2012 Hub centric should be to balance the wheels shouldn't need rings on the car Quote Link to comment Share on other sites More sharing options...
Xxyyzz Posted November 13, 2012 Author Share Posted November 13, 2012 Even if it hubcentric, couldn't it be the wrong center bore? IE: too big Quote Link to comment Share on other sites More sharing options...
stangeba Posted November 13, 2012 Share Posted November 13, 2012 Interesting discussion. I have never even heard of these things till now but I understand that it is important to have the center of the wheel fit snugly on the hub, for correct fit and proper strength and durability. I have only ever used stock wheels on all my cars. I remember mid 70's Ford had problems with their aluminum wheels corroding and sticking to the hubs when people didn't rotate their tires and with SALT on the Michigan roads in the winter. Very hard to remove those things! Bruce Quote Link to comment Share on other sites More sharing options...
71 MONTE 4 YA Posted November 13, 2012 Share Posted November 13, 2012 Even if it hubcentric, couldn't it be the wrong center bore? IE: too big The hub centric rings will fit inside the center bore of the wheel and take up the space to make the wheel fit tightly around the hub.

monte70car Posted November 14, 2012 Share Posted November 14, 2012 I don't think those wheels are hub centric as its lug centric. If the shop is going by the the center opening there is a large center cap that goes there saying Cragar . The rim itself rest on the lug nut studs.

If the shop is going by the the center opening there is a large center cap that goes there saying Cragar . The rim itself rest on the lug nut studs. All wheels are lug-centric. If the lugs were not radially spaced centric to the wheel, you would have a pretty awful wheel, let alone ride. I'm not sure if it was mentioned before, but I'll say it anyway (I skimmed pretty quickly). The hub opening needs to be perfrectly concentric to the wheel as the wheel balancer clamps the wheel onto a tapered shaft surface. Quote Link to comment Share on other sites More sharing options...
wallaby Posted November 14, 2012 Share Posted November 14, 2012 Yea, I don't get it. If they can't mount the tire on their balancer, then why do YOU need to get the adapter to make it fit? If this is only needed for the purpose of balancing...But looking at the catalog I see they only cost about $2 each and are made of plastic? Your wheels are supposed to be centered by the lug nuts, and don't need to fit snug in the center on the hub. I've seen wheels where the center hole isn't even close to being round... Those are a bugger to balance with the typical cone-type centering tools that balancing machines use. Here is an example: The inner side of the hole has like 4 curved sides, and the outer side of the hole is so small that the thru-shaft on the balancer barely fits through...no room for even a tiny cone there, but there is considerable slop making it impossible to mount straight. Find out from your shop WHY they recommend the hub centric rings. Quote Link to comment Share on other sites More sharing options...
Leghome Posted November 14, 2012 Share Posted November 14, 2012 I remember seeing some wheels a few years ago that the lug holes were elongated. I could wee where these hub centric rings would be needed on wheels like that. The lug nuts for these wheels were supposed to line everything up but I have seen them fit loosely when the wrong nuts were used. Quote Link to comment Share on other sites More sharing options...

The lug nuts for these wheels were supposed to line everything up but I have seen them fit loosely when the wrong nuts were used. The elongated ones were universal wheels. I've seen ones that fit a 5x4 3/4 and a 5x4 1/2 lug pattern, the center was not hub centric either. They need a shank style lug nut to hold them in place.

7tonemonte Posted November 14, 2012 Share Posted November 14, 2012 I had a set like the ones Bill pictured on an old Duster I had.

Ian Posted November 14, 2012 Share Posted November 14, 2012 I had a problem with balancing Wheel Vintiques ralley wheels before because they were not hub centric, I ended up having them balanced on the car by the old guy at the tire shop.

I believe I bought a Wheel Vintiques rallye for my full-size spare and it was balanced without fuss. Quote Link to comment Share on other sites More sharing options...
Ian Posted November 15, 2012 Share Posted November 15, 2012 I had them balanced when I got them, then had a vibration. Had them checked at the same shop that balanced them the first time and they were off... Rebalanced and still had the vibration. After having them done on the car vibration went away for the most part... Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted November 19, 2012 Share Posted November 19, 2012 Factory wheels center on the hub and are hub centric without rings. Some aftermarket wheels are hub centric (centered on the hub) because the wheels fit a variety of manufacturers they use a spacer ring or centric ring to center the wheel on the hub. The wheel manufacturer will be able to supply the right ring. Some aftermarket wheels center on the lugs. be careful mounting the wheels snug all the lugs before tightening to the correct torque.
