I beleive you have a bad tire. I even had it on a balancer and it spun good. It would only do it on the car with the weight on it. ( Went thru this crap on my wifes car ) I learned something on that one.

Changed tires now to 3 different combinations, same symptoms, though slightly better (less violent) the larger the tire I used. Two of the sets were 2010 dated tires (the larger ones) the small sets were a real miss-match (2007 & 2009 dated).
