BMW: shakes at high speed, tire shop, e30

Question
hey, I have an 1987 e30 325e and it shakes at speeds higher than 80 mph. What do you think it could be, maybe the bearings? let me know what you think?

Answer
Shahab,
 There are many things this problem could be.  Most likely you need your wheels balanced.  I would take the car to a tire shop and have them balance the tires.  This should fix most of the problem.  If you still get a vibration, it could be that your wheels have a bent spot in them.

 Good luck,
 Josh
