DC10 FLC RAN OFF SIDE OF TXWY WITH 1 OUTSIDE MAIN GEAR TIRE WHEN TURNING ONTO TXWY AFTER LNDG.

Narrative

AFTER LNDG RWY 27L IN CDG; ACFT CLRED HIGH SPD TAXI WHICH LED DIRECTLY INTO CARRIER'S RAMP. ANOTHER CARRIER WAS TOWING A B747 FROM A HANGAR ON THE ONLY INBOUND TXWY WHICH LED TO CARRIER'S RAMP. CDG GND CTL INSTRUCTED ME TO TURN R ON TXWY B. THERE WERE 2 CROSS TXWYS -- TXWY B AND TXWY D. BOTH WERE MARKED (NOT CLRLY) NO TURNS TO WDB ACFT. HOWEVER; GND INSTRUCTED US TO TURN ONTO TXWY B. WHILE ATTEMPTING THIS TURN; RFO POINTED OUT TURN MARKED ILLEGAL ON COMMERCIAL CHARTS; HOWEVER; ACFT ALREADY IN THE TURN. OVERSTEARED ACFT AS MUCH AS POSSIBLE; BUT 2 OUTBOARD WHEELS OF R TRUCK RECEIVED SLIGHT MUD ON TIRES; NO DAMAGE! THIS IS AT THE END OF 2 INTL LEGS AND 12 HR 30 MIN DUTY PERIOD WHICH BEGAN AT XA00. THE B747 QUESTIONED GND CTL WHILE BEING TOWED AS TO WHERE WE WERE GOING; AND GND CTL INFORMED THEM NOT TO WORRY; WE WERE TURNING R ON TXWY B -- FURTHER LEADING US INTO THE ILLEGAL TURN. CDG GND USES MULTIPLE LANGUAGES. TXWYS ARE POORLY MARKED AND MANY ARE ONE WAY; YET CDG GND MAY SEND YOU WRONG WAY ON 1-WAY.
