I had horrible issues with mine when I changed wheels and tires. It took 3 sets of tires to get something remotely acceptable and then I still wound up taking it to the dealer for a road force balance. No problems since. Another theory I have heard is the lower control arm bushings are too soft. And they definitely are. I swapped mine out for whiteline urethane bushings and the steering response and overall tracking is so much better. I don't have balance issues currently but my tires are chopped from a poor alignment (same shop that couldn't balance 3 sets of tires) so chances are I will be doing tires again before long. I'm not terribly impressed with the snow or off road performance of the AT3 Toyos. Probably will go back to KO2's or Grabber ATX's
