Do you guys think this is necessary? I've had bad tires (Fuzion) on my civic and had a tire store re-balance them twice using a non-road force machine. I then went and had them road force balanced and the tech told me they were out of round. I then used my own non-road force balancer and basically matched the road force machine as far as the vibration at ~70mph it was having. I know the road force machine can actually tell you where to mount the tire for less un-eveness. Does anyone think road force is necessary to balance or hint that the tire is out of round or is it a given that the tires need to be replaced when a standard balancer can't get it balanced multiple times?
