It's your balance. I know few people that got new tires and balance and the car was shaking/vibration like crazy.

""""Front wheels have 1 and 2 lb of road force, tech said it was the lowest he had seen""" you kidding me? That's crazy amount of weight, your rims are bent, or he balanced wrong. I worked as a mechanic for 5 years and I never seen that much weight on one rims. Most I seen just over 4oz and that's on trucks 1500/2500 and that's about 1/4 of a pound.
