When I get on the highway, I get up to 70-80mph and the car starts to vibrate heavily. Not a real serious vibration, but enough to where I cannot ignore it.

I've since had the wheels rebalanced and the tires are slightly brand new (bought the tires almost 4 months ago). I'm kind of hoping it's nothing real serious because I don't have much money right now because I am unemployed.
