Narrative:

On takeoff roll at approximately 120 KTS; both first officer (PF) and captain (PNF) noticed the aircraft yaw to the right. First officer increased rudder pressure to realign aircraft with centerline. He verbally indicated to captain that increased rudder pressure was necessary and got greater up until aircraft rotation. After liftoff; all flight and system indications were normal. Concerned about possible tire failure; captain radioed ZZZ to have them inspect runway for debris. Tower indicated after inspection that no debris had been found; but that they had been notified by ZZZ police that someone had called and reported seeing 'something hanging from the fuselage of our aircraft' as it flew over on departure. After consulting with dispatch; maintenance controller; and operations; the actual cause of the yaw and the subsequent report of an abnormal appendage could not be determined. The crew determined that the safest course of action was to declare an emergency; continue to destination so as to burn down to a lighter weight; and land under a cabin advisory with the flight attendants. The crew also chose to do a fly-by of the runway at ZZZ1 so that ground personnel could report of anything appeared abnormal with the exterior of the aircraft or the landing gear. After the fly-by; a normal landing was accomplished and the aircraft was taxied to the gate without incident.

Title: AN AIRBUS 320 ON TKOF ROLL YAWED TO THE R AND CREW SUSPECTED A FAILED TIRE. DECLARED AN EMER AND CONTINUED TO THE DEST TO BURN OFF FUEL. LANDED UNEVENTFULLY AND NORMAL TAXI TO GATE.

Narrative: ON TKOF ROLL AT APPROX 120 KTS; BOTH FO (PF) AND CAPT (PNF) NOTICED THE ACFT YAW TO THE R. FO INCREASED RUDDER PRESSURE TO REALIGN ACFT WITH CTRLINE. HE VERBALLY INDICATED TO CAPT THAT INCREASED RUDDER PRESSURE WAS NECESSARY AND GOT GREATER UP UNTIL ACFT ROTATION. AFTER LIFTOFF; ALL FLT AND SYS INDICATIONS WERE NORMAL. CONCERNED ABOUT POSSIBLE TIRE FAILURE; CAPT RADIOED ZZZ TO HAVE THEM INSPECT RWY FOR DEBRIS. TWR INDICATED AFTER INSPECTION THAT NO DEBRIS HAD BEEN FOUND; BUT THAT THEY HAD BEEN NOTIFIED BY ZZZ POLICE THAT SOMEONE HAD CALLED AND RPTED SEEING 'SOMETHING HANGING FROM THE FUSELAGE OF OUR ACFT' AS IT FLEW OVER ON DEP. AFTER CONSULTING WITH DISPATCH; MAINT CTLR; AND OPS; THE ACTUAL CAUSE OF THE YAW AND THE SUBSEQUENT RPT OF AN ABNORMAL APPENDAGE COULD NOT BE DETERMINED. THE CREW DETERMINED THAT THE SAFEST COURSE OF ACTION WAS TO DECLARE AN EMER; CONTINUE TO DEST SO AS TO BURN DOWN TO A LIGHTER WT; AND LAND UNDER A CABIN ADVISORY WITH THE FLT ATTENDANTS. THE CREW ALSO CHOSE TO DO A FLY-BY OF THE RWY AT ZZZ1 SO THAT GND PERSONNEL COULD RPT OF ANYTHING APPEARED ABNORMAL WITH THE EXTERIOR OF THE ACFT OR THE LNDG GEAR. AFTER THE FLY-BY; A NORMAL LNDG WAS ACCOMPLISHED AND THE ACFT WAS TAXIED TO THE GATE WITHOUT INCIDENT.
