I had this problem also where my car would shake between 55-75. It ran smoothly at 80 (don't tell the CHP). Everyone I asked said tires, so I had the tires balanced and realigned, but that didn't fix it. Most of the mechanics I asked were stumped. Finally someone recommended having the struts looked at and sure enough, I had the struts replaced (the car had 70,000 miles on it) and it worked. I have never had this problem since (now the car has 150,000). I have sold tires for a number of years and I can assure you sometimes new tires can be out-of-round. Take it back and demand that this problem be resolved. Mark
Usually caused by spark plugs not igniting properly. Check that your spark plugs and and your spark plug wires are in tact and working.
If it only happens when you accelerate the most likely cause is an axle.

Some parts stores will scan your vehicle for free. Advance auto for one.
Your car is not getting enough fuel if it hesitates to take off and shakes. The fuel filter might be plugged or you might have the wrong gas in your tank.
Need more info like what is the vehicle doing when it shakes, is it idling in park, driving down the road, braking, driving at highway speeds, etc.
