Narrative:

While taxiing to runway 3C at dtw, I made a r-hand turn from taxiway F onto taxiway M. The right main departed the paved surface. I thought I had run over something on the taxiway. I stopped the aircraft. The tower asked if we needed help from our company maintenance. We asked what for and they responded that the right main (outboard wheels, I understood them to say) were off the taxiway. We said we didn't think we needed any help. We were in the process of starting the #2 engine and continued. The aircraft taxied out under its own power with very little more than normal breakaway thrust. I continued to the run-up pad and we called maintenance to come out and inspect the gear. After they checked it, we taxied to gate for the required maintenance. Supplemental information from acn 299407: need: wider taxi area at location, clear taxi markings in all conditions.
