## Discrepancy

AFTER LANDING IN MMPR, WHILE PERFORMING THE WALK AROUND INSPECTION, THE CAPTAIN NOTICED A SECTION OF THE TREAD MISSING ON THE NR 1 MAIN TIRE.  NO OTHER DAMAGE WAS REPORTED BUT THE TREAD SEPARATION.  THE CAUSE OF THE TREAD SEPARATION COULD NOT BE DETERMINED.  MECHANIC TO REPLACED THE BAD TIRE.
