Wheel shake after balancing
 

I recently bought a very nice set of used rims that had yokohama parada spec 2 already on them... The tires seemed to be almost brand new.. But when I first put them on, there was just a tiny bit of wheel shake, so I thought I would get them balanced just to be safe... After the balancing, the wheel shake is almost dangerous.

Ether my shop doesn't know how to balance tires, or the tire was balanced, relative to it's wear, and I mucked it up..

When I bought the tires, only one rim had any kind of balancing weight on it..

So I'm not sure what to do now.. Take them to a different shop to see if they are balanced... or take the weights off, and try to put them back the way they were..

Would rotating my tires help me any?

I've been reading about out-of-round tires, and I don't think it the case.. My car only shakes from 80 to 115, past 120, it's very smooth..

I thought wheels out of balance will only increase roughness as speed increases. You can just mount tires and drive without balancing, but only travel at low speed.

You may have other issues.

I would say the used rims are dented or warped!

They could be out of round. Have the shop put them on the balancer and as it turns you can watch if it bumps around.
If they balance it again and it's still messed up try breaking the bead from the rim and turning the tire 180 degrees on the rim, then rebalance and retest. If that fixes it, problem is most likely the tire.

bent rim, shifted belt, not balanced properly, etc.. just take it back to the shop

So I took my rims into Honda, and the first thing they said was "Where are your centering rings?"

So turns out I need Hub Centric Rings.

Does anyone know, and I'm just looking to confirm, that a 2003 Civic has a "Hub Ring" Diameter of 56.10mm

Not sure if it's really called a Hub Ring, but I don't know what it's really called, and I think people here will understand.

I only ask because I'm having a hard time finding a Hub Centric Ring with an Inside Diameter of 56.10mm with a Outside Diameter of 73mm.

The best I can find is 56.15.. Do you know that the 0.05mm will make a big difference?

There are metal or hard abs plastic rings out there.

The 0.05mm is fine. I would believe the difference is good for fitting and metal expansion.
