This will make the tire very unstable and impossible to balance = the steering vib. which is why i ask to swap wheels, its a quick way to eliminate a bent wheel/tire issues. If the whole car shakes then most like the rear wheels are out of balance.
I wish I would have taken this advice a while back....instead I checked everything else and it ended up being my rim lol!
