Narrative:

Landed kaus. Runway 31L was wet from earlier storm. Did not make runway 17 turnoff so rolled to end of runway 31L. At proper taxi speed, made left 135 degree turn onto taxiway H, which is very narrow. Evidently left 2 tires on left main truck left taxiway by approximately 2 ft into grass area. Right 2 tires left main truck remained on taxiway. Crew felt no excursion. Post-flight inspection revealed no dirt or damage. Next morning station personnel found dirt/mud on left tires and reported same. No damage to aircraft and it departed on schedule. Captain called by chief pilot , dfw as to what had happened. Check airman sent to line-check captain, aus-dfw. Captain and check airman personally inspected excursion area. Tire tracks 2 ft from taxiway indeed showed minor excursion. Captain reported this incident to dispatch and issued pilot alert to all aircraft landing aus and exiting end of 31L. Suggested pulling right of centerline before initiating turn onto taxiway 'H' to preclude any similar incidents. This taxiway, with 135 degree turn, especially at night, is unsuitable for widebody transport type aircraft. Airport needs to take corrective action and also NOTAM this exit from runway 31L. Rebuilding this area is in order. Also, note needs to be made on appropriate airport page. Particularly misleading at night as to area of safe turn capability, especially for widebody transport type aircraft.
