My partner and I were assigned to move another company's aircraft from one terminal to another. My partner was in the left seat and I was in the right seat. After push back we notified International tower ready to taxi they gave us instructions to move forward on the international ramp and hold short of taxi way and to contact ground. We moved forward to hold line; I called ground and we were given instruction to taxi. We proceeded on our move and after we made the turn on the taxiway; I noticed a status message come up 'Tire Pressure' I switched to the gear page and noticed #12 tire lost pressure. We continued to the gate and found Damage to #12 and #8 sidewalls and replaced tires #8; #11 and #12.Improved situational awareness in the cockpit. Better route via taxiway and light boxes being put flush in the taxiway.
While performing a taxi move of a B777 from one Terminal to another; turning west onto from one taxiway to another; I contacted a taxiway edge light assembly with the right main landing gear causing damage to two tires.I have been ill with cold/flu symptoms for the past five days. I had taken one sick day to rest. I worked a swing shift two nights later. I believe limited sleep the night before the incident and still feeling the effects of mild illness may have played a role in this incident. I was not on cold/flu medication on the day of the incident. Longer rest the night before or not working when still feeling less than 100% due to illness may have helped avoid this incident.
Contract Technician reported the right Main Landing Gear of a B777 contacted taxiway edge lights and damaged three Main Landing Gear tires during a taxi move.
