hi, I have a set 265/75/16 bfg tyers and genuine 16inch xs wheels, for some strange reason they will not balence on a machine, I have tryed many different tyre fitters and no joy, if you take the weights off and start fresh, put the wheel on a machine, then put the weights to where it states, spin again and then it comes up as balenced, take the wheel off, rotate it, put it back on machine spin it, then it will be out by a good bit, the problem I am having the wheels are eating the pas drop arm, and panhard bushes, give it a couple of months after renewing the l/r shakes badly after 35mph, please help
