I asked this a long time ago, but I'm just wondering if anyone has had this problem in the interim. Anybody out there having routine problems balancing the IS 17" rims? I have 5K miles on the car and I've had it into the dealer 3 times to have the wheels balanced because of a chimmy in the steering wheel at certain speeds. Every time the balancer recommends a new position for the weight. This is getting frustrating. Could I have a bad tire??
