Narrative:

We experienced some vibrations that appeared to come from the nose gear at rotation. Shortly after departure tower advised us that a departing aircraft behind us saw tire debris on the runway. With the vibrations experienced and evidence of tire debris on the runway after our departure; we had reason to believe we had blown a tire. We decided to continue to our destination since they had longer runways and better crash/fire/rescue. We briefed the flight attendants of the issues at hand and informed them to prepare the cabin for an emergency landing. An emergency was declared and we followed the emergency checklist for abnormal gear. To get more information on the condition of the tires we coordinated a fly-by with the tower. The tower informed us that everything seemed normal from their position and that an aircraft awaiting departure agreed that the gear and tires appeared normal. We circled over and landed without incident. It was not until we got to the ramp that it was confirmed that the tread on the number 3 tire had come off.
