## Discrepancy

ACFT DEPARTED LIML.  CREW WAS CONTACTED ABOUT 2 HOURS AFTER DEPARTURE BY ATC INFORMING THEM THEY MIGHT HAVE BLOWN A TIRE ON TAKEOFF.  CREW LOOKED AT TIRE PRESSURE IN FLIGHT AND CONFIRMED ALL TIRES STILL HAD GOOD PRESSURE.  INTERNATIONAL HANDLER CONTACTED CREW A LITTLE WHILE LATER AND CONFIRMED VIDEO EVIDENCE OF TIRE COMING OFF DURING TAKEOFF.  NO DEFECTS WERE FOUND DURING PREFLIGHT AND TIRE PRESSURE WAS GOOD.  CREW FOLLOWED CHECKLIST AND NOTIFIED ATC OF SITUATION WHILE ON DECENT INTO KSJC.  A NORMAL LANDING WAS PERFORMED, AND POST FLIGHT INSPECTION WAS PERFORMED.  THE #1 MAIN TIRE HAD LOST THE TREAD IN THE CENTER SECTION OF THE TIRE DOWN TO CORD DURING TAKEOFF.  NO OTHER DAMAGE WAS NOTED.
