20" Wheels = Shaky Steering??

Thanks for the info, Wolf. I dont see hubcentric rings mentioned in your post, and this thread is the first mention I've seen of them. Are they necessary for some replica wheels for the reasons you mentioned?

From what I gathered at various places today, the answer is 'sometimes'. It sounds like they help compensate in certain situations. My guy at the tire place who's going to do the mount/balance said he'll see what they (wheels) look like when they get here. I just ordered some from Lakeshore Wheel and Tire in MI (ebay) for $975 shipped. Jason at LWT said that they don't need hubs, so we'll see. He also told me that each wheel they ship is spun-out previous to delivery. I'm keeping my fingers crossed on this deal!

On second thought, it looks like my Style 177 rims are supposedly 72.56mm center bore already!?

I think i am going to measure them. I don't trust WAC. If this is correct than either one or more of the rims are out of round, or weren't balanced properly.

This sucks... don't buy replicas.

I bought a set of AFS wheels and tires. AFS did a wonderful job mounting and balancing the tires. No problems. They are perfect!!!

Madforce - Amazing, I had a completely different experience with AFS. I emailed multile times and each time received a prompt response. I would definitely buy AFS again.....

Yes we350z, do measure by all means. If you're not right on 72.56mm then you'll definitely need the hub rings. Hunter 9700 series is great by the way...good luck!

If anyone is reading this, I would not suggest getting replicas even though the ones I have are headache free. This is also a great thread.

It sounds like they are all hit or miss. I have heard good things and bad things about all of the companies now.

Just got off the phone with a local professional tire shop which I setup an appointment with next Saturday. They said that the likelihood that the wheels are either out of round, or machined improperly (center bore, lug holes) is not very high even with replicas. Anything is possible, but he said that one would experience a costant wobble or hard shaking at pretty much all speeds instead of intermittent vibration. He went on to say that it is likely to be one or more of the following factors:

1) Wheels are not hubcentric to the hub. The wheel centerbore supposed to be 72.56mm, so either it is mis-stated or was not accurately machined. if its 74.1mm+ rings can be used. This can be determined by measuring with a digital caliper and/or unbolting the rim and seeing if it has any play around the hub center.

2) Vehicle road downforce can contribute to vibrations. Especially if the vibrations are intermittent and typically go away by driving faster. Balancing, while important (and you should use a Hunter GSP9700) is not often the contributing factor here. The tire and the rim each have a high point and a low point, and in relation to each other they need to be offset for optimal handling and tire wear.

I got a digital caliper and i am going to dismount the rims to measure them all and see how they fit on the hub center. Worth a shot, hopefully the problem can be resolved.

If so I am debating powder coat vs. painting.

Did you ever get this resolved? What was the issue?

When I threw my 22in Nad4's on my X5 I was stupid and did not get an alignment. I noticed some similar symptoms, I took it into a shop called TruLine in bellevue, wa. They were great. They aligned the truck and also fixed my cv boot. Both of these dramatically improved the issues I was having...
