If the tires are good, the rims are not bent, and the tread on the tires isn't cupped or worn unevenly, my guess is that you have a worn motor mount. They ride in rubber mounts that are there to absorb engine vibration. If the rubber is worn or bad, you get a metal to metal contact and can feel the engine vibrations throughout the car. Have that checked.
