K, I just put new wheels on my car, the lug nuts are tight as can be, they aren't out of balance and they aren't bent b/c they were fine on the other car.. Here is what it does:

When I'm driving the steering wheel shakes, and the wheel LOOKS bent but isnt.. When I get up to about 45-50mph it makes a sound like its hitting something (knocking sound, but not the motor) and squeaks.. Also when the car is on the ground, u kick the tire and it shakes a little and if you jack it up, and shake the wheel it shakes. My old wheels didn't do this and these wheels didn't do this on the car they came off of.. What in gods name could it be?? loose tie rod or something?
