I agree with Displayname--road force balancing is THE was to go if you suspect wheel problems. I got a set of fairly expensive wheels for my other car a couple of year ago (took me 6 months to get them!). After a road force balance, I found out that the wheels were actually egg shaped and it was impossible to proper;y balance them as a result. So I had to wait another 3 months until I was able to put the wheels on the car! Grrr!!!
