What was found
LEFT HAND TIRE TREAD DEPARTED THE TIRE AFTER TAKEOFF. THE CREW GOT A ANTISKID FAILURE CAS MESSAGE DISPLAYED SHORTLY AFTER TAKEOFF. THE CREW DISCOVERED THAT THE FLAPS WERE SLIGHTLY AFT OF THE FULLY STOWED POSITION. THE HYDRAULIC AMBER PRESSURE CAS MESSAGE STAYED ON AND THE CREW WENT THROUGH THE CHECKLIST AND ENTAILED PULLING BREAKER FOR HYDRAULIC CONTROL BREAKER SO THE PUMP DOESN'T RUN CONTINUOUSLY. AFTER A NORMAL APPROACH AND LANDING GOING INTO KCMH, IT WAS DISCOVERED THAT THE TIRE TREAD HAD LEFT THE TIRE AND DAMAGED THE FLAP DOING SO, ALONG WITH THE ANTISKID WIRE.
