I sometimes (but not always) notice the steering wheel shake ever so slightly at lower speeds (apprx 40 MPH). I have also driven my car at 100 MPH and there was no shimmy in my steering wheel. The car also tracs straight at all speeds. The BMW dealer said that there is a slight bend to the right front and rear rims, although I can't see it. Is it crazy for me to spend $1,200 (rims, balancing, alignment) if I can only occasionally notice this? I just replaced all 4 tires and had them balanced as well. Any suggestions?
