RE: vibration in wheels
I kinda doubt it. Only reason we have one is our company has been around for 30 years and have some neat old school stuff like that.
Close to Chicago? gimme a pm we can take a look.

The most common problem that leads to this problem is that they were "Statically" balanced. That means that they only put weights on the inboard rim. This will balance the wheel keeping it from hopping up and down but will often allow it to wobble. Wheels MUST be balanced "Dynamically" meaning weights on both inboard AND outboard planes.
The shops won't do this unless you ask because they don't want to scratch the wheels. To keep from using clip on weights that will indeed scratch the wheels, a savvy wheel balance guy will use tape weights just behind the spokes for a dynamica balance.
If there are indeed weights on the inboard and outboard planes of the wheels, go to www.gsp9700.com and find the nearest GSP97000 Hunter machine with a knowledgable person running it. These machines not only do a dynamic balance but also have a pressure roller that can analyze the tire for Road Force Variation(RFV) which are basically stiff spots.
Unless you have worn suspension parts needing alignment to mask the ill effects of same, alignment will NOT correct vibration issues.

RE: vibration in wheels
yeah they said they used the GSP9700 and road force tested it and it was from 12-18 pounds within spec (whatever that means) and they put a couple weights on the inboard side...they mentioned that they did statically balance the wheel. but i didnt see any sticky tape weights on the outboard side....i dont know if they dynamically balanced the wheel. im assuming that they did both since they used that hunter machine speicifically.
is there anything i can do at this point? the guys at the shop were like, yeah those are 20s with low profile tires, they're gonna have vibration...i rolled my eyes but there isnt a whole lot i can do i dont think. ive taken it to the custom shop like 3 times to get the wheels balanced and they failed. so finally i took it to the dealership wheel shop and they used the road force thing to balance the wheels. i figured they would've been able to solve the vibration problem but no luck.
this is frustrating as hell.

"Let's see, the clips are KNOWN to cause vibration... Hmmmm.... no, I won't remove the clips. I wonder why I still have a vibration problem..."

wow...what an old thread...
if it's only been 3 months, yes, after driving it, the flat spots should go away..
are you talking about hub rings?
