It seems when the tire dealer re-installed th stock tires, he failed to do the same thing on each side; i.e., he moved one former rear to the front, without doing the same to the other side. Tires must be kept on the same side AND the same axle.

So, when you feel like you're out of control, or simply tenoidng toward one side and the other, check your last tire rotation. This car, whether due to its larger radius tires, and/or it short wheelbase, has different dynamics than other vehicles.

And...both the Isuzu and tire dealer said that a misbalance, would not cause the loss of control. Really? KNOW THY VEHICLE!
