Mickey Thompson Tires "Suck"

I wish I would have read this thread before today. I went to work today and mounted my new P325/50R/15 MT ET Street radials on brand new Center Line wheels. We tried to balance them on our Hunter wheel balancer. The balancer was calling for over 300 grams of weight!! We tried playing with different positions but it made no difference.

I am still in the mock up process but am wondering whether I need to contact Summit or MT about returning these tires? One of the old guys said that since they are going on the back, I should just static (bubble) balance the tires and live with them. I paid $200 a piece for these tires and don't think I should have to compromise anything!!!

What do you guys think?
