Narrative:

On flight we had a normal takeoff and were climbing out of san when tower called. They said we lost a tire on takeoff. We had already retracted the gear and had the flaps at 5 degrees. Since hydraulic qty and pressure were normal, we retracted the flaps all the way. We decided to climb to cruise and contact the company for assistance. After consulting with maintenance and boeing, we continued to atlanta. The aircraft was operating fine and we wanted to land lighter. We burned about 35000 pounds going coast to coast. Boeing suggested an unsafe gear landing. We declared an emergency and landed on runway 9L, the longest runway. The gear was inspected and pinned. The #5 tire and wheel were on the ground in san diego. Callback conversation with reporter revealed the following information: after landing at atlanta, and on inspection of the axle, the only component remaining was the inner bearing. The direct cause of the wheel departure is under investigation and no findings have been announced.
