Narrative:

Inboard main wheel and assembly departed aircraft on takeoff. Crew received no cockpit indications. Received ACARS message approximately 10 mins later stating we may have a wheel problem. Later ACARS message stated it was an medium large transport a wheel. This aircraft was medium large transport B. I flew aircraft most of way to dtw while captain tried to ascertain with company if it was our plane. About 10 mins out from dtw the company confirmed they had our wheel and wanted us to fly over dtw for EMS verification. We did and they confirmed our left inboard main was gone. The captain then stayed in pattern for visual 21L. The surface winds were strong out of west allowing captain to land with initial touchdown on right main. We landed with no problem and had EMS inspect wheels. Then we taxied to gate. Note: company memo indicated that the transducer in the hub may have been seated improperly creating excessive vibration. They indicated there was no problem with supporting nut.
