1. The tires you bought are junk or not balanced properly.

2. A rim is bent.

3. The drum or rotor is out of round.

4. The driveshaft weight fell off or the U-joint has slop in it.

You can turn OFF the engine while you are driving (place the transmission in N) to eliminate engine vibration. Then, move the tires front to rear to see if it helps. I had a vibration in my 85 Firebird once which turned out to be a drum.

GM dealers have an Electronic Vibration Analyzer. Based on the frequency you can tell if its coming from the engine, transmission, driveline, wheels or some other source like brakes.
