CRJ900 flight crew notes unusual vibration during takeoff and continues. During climb a flight attendant reports there was also an unusual sound in the cabin and the crew elects to contact dispatch. Suspecting a blown tire; the decision is made to return for an over weight landing. The other tire on the affected gear deflates on the way to the gate.

Narrative:
On takeoff roll at 100 KTS; aircraft made an unusual shake. No directional problems or engine indication problem. Continued takeoff and climbing through 10;000 ft the flight attendant advised us of an abnormal sound prior to takeoff. Called dispatch and advised them of probable blown tire. [We] discussed our options with flight control and maintenance. [We] made the decision to return. [We] discussed overweight landing with dispatch and maintenance. Maintenance asked us to note vertical speed on landing and had no issue with overweight landing. [We] declared emergency with ATC. [We] made an overweight landing on 79;000 pounds card. Cleared the runway and fire crew advise left inboard tire was flat. I taxied slowly to gate. On taxiway prior to entering ramp left outboard main deflated. [We] secured aircraft; bussed passengers to terminal; and turned aircraft over to maintenance. I should have burned off the fuel and not landed overweight. Dispatch mentioned the time it would take to burn off the fuel. Maintenance stated they saw no problem with overweight landing. Just to note the vertical speed. If I had it to do over again I would have burned the fuel down to landing weight.
