Narrative:
We landed on runway 5R. We turned off taxiway A8, a short connecting taxiway. The aircraft was stopped while we called our ground handlers for a parking location. When we received the location, we requested clearance to continue taxi. During the right turn onto taxiway a, I noticed the right gear was dragging. I added power on #3 engine and questioned whether we may have flat tires on that side. Soon the aircraft taxied quite easily and I then thought maybe we had gone off the taxiway. I believed at first we were appropriately on the taxiway. Perhaps a combination of a dark ramp directly ahead of us while on taxiway A8 as well as the short connecting taxiway and inability to see the taxiway edge lights on the right side fooled my eyes. A check airman was in the front jumpseat and made no comment that the turn looked tight. Post-flight inspection showed mud on all right gear tires plus mud impacted into brakes #7 and #8. Tire #7 needed to be replaced. It was damaged possibly on the taxiway light that was damaged. With an extremely short connecting taxiway, it is impossible to see the outside lights of the taxiway. Perhaps a short lead in centerline taxiway light would help. It may also help to have the ramp directly to the front of taxiway A8 at least dimly lit.

Title: AN ACR DC10 GOT ITS R MAIN GEAR OFF OF THE TXWY WHILE MAKING A SHARP R TURN. NIGHT OP. TAXIING TFC.
Narrative: WE LANDED ON RWY 5R. WE TURNED OFF TXWY A8, A SHORT CONNECTING TXWY. THE ACFT WAS STOPPED WHILE WE CALLED OUR GND HANDLERS FOR A PARKING LOCATION. WHEN WE RECEIVED THE LOCATION, WE REQUESTED CLRNC TO CONTINUE TAXI. DURING THE R TURN ONTO TXWY A, I NOTICED THE R GEAR WAS DRAGGING. I ADDED PWR ON #3 ENG AND QUESTIONED WHETHER WE MAY HAVE FLAT TIRES ON THAT SIDE. SOON THE ACFT TAXIED QUITE EASILY AND I THEN THOUGHT MAYBE WE HAD GONE OFF THE TXWY. I BELIEVED AT FIRST WE WERE APPROPRIATELY ON THE TXWY. PERHAPS A COMBINATION OF A DARK RAMP DIRECTLY AHEAD OF US WHILE ON TXWY A8 AS WELL AS THE SHORT CONNECTING TXWY AND INABILITY TO SEE THE TXWY EDGE LIGHTS ON THE R SIDE FOOLED MY EYES. A CHK AIRMAN WAS IN THE FRONT JUMPSEAT AND MADE NO COMMENT THAT THE TURN LOOKED TIGHT. POST-FLT INSPECTION SHOWED MUD ON ALL R GEAR TIRES PLUS MUD IMPACTED INTO BRAKES #7 AND #8. TIRE #7 NEEDED TO BE REPLACED. IT WAS DAMAGED POSSIBLY ON THE TXWY LIGHT THAT WAS DAMAGED. WITH AN EXTREMELY SHORT CONNECTING TXWY, IT IS IMPOSSIBLE TO SEE THE OUTSIDE LIGHTS OF THE TXWY. PERHAPS A SHORT LEAD IN CTRLINE TXWY LIGHT WOULD HELP. IT MAY ALSO HELP TO HAVE THE RAMP DIRECTLY TO THE FRONT OF TXWY A8 AT LEAST DIMLY LIT.
