Narrative:

During takeoff from runway 8; I saw what appeared to be a piece of tire rubber bounce past the right side of the airplane. We were at approximately 130 KTS (below V1). We had a normal takeoff with no indications of a problem with our airplane. I reported the foreign object damage to the tower and they said they'd check it out. After consulting with ATC and dispatch en route; we determined that the rubber was probably from our airplane and from a main gear tire. After discussing divert options; we decided to continue. The captain advised the lead flight attendant of the situation and had her perform a cabin preparation. We asked for the fire trucks to be standing by upon arrival. I gave the 'brace' call over the PA at 100 ft and a 'remain seated' PA call during rollout. The landing was uneventful and we felt no vibrations; shimmies; noises; etc. After having the firemen do a cursory inspection of the tire; we decided it was safe to taxi to the gate. Upon inspection we found the tread from the inboard right tire had separated. There was a dent in the bottom of the wing from debris impact (about 6 inches long and a couple inches deep). There were signs of other potential impact damage that the mechanics were evaluating when we left.

Title: A320 FLT CREW DURING TKOF ROLL OBSERVES RUBBER TREAD DEPART ACFT.

Narrative: DURING TKOF FROM RWY 8; I SAW WHAT APPEARED TO BE A PIECE OF TIRE RUBBER BOUNCE PAST THE R SIDE OF THE AIRPLANE. WE WERE AT APPROX 130 KTS (BELOW V1). WE HAD A NORMAL TKOF WITH NO INDICATIONS OF A PROB WITH OUR AIRPLANE. I RPTED THE FOREIGN OBJECT DAMAGE TO THE TWR AND THEY SAID THEY'D CHK IT OUT. AFTER CONSULTING WITH ATC AND DISPATCH ENRTE; WE DETERMINED THAT THE RUBBER WAS PROBABLY FROM OUR AIRPLANE AND FROM A MAIN GEAR TIRE. AFTER DISCUSSING DIVERT OPTIONS; WE DECIDED TO CONTINUE. THE CAPT ADVISED THE LEAD FLT ATTENDANT OF THE SITUATION AND HAD HER PERFORM A CABIN PREPARATION. WE ASKED FOR THE FIRE TRUCKS TO BE STANDING BY UPON ARR. I GAVE THE 'BRACE' CALL OVER THE PA AT 100 FT AND A 'REMAIN SEATED' PA CALL DURING ROLLOUT. THE LNDG WAS UNEVENTFUL AND WE FELT NO VIBRATIONS; SHIMMIES; NOISES; ETC. AFTER HAVING THE FIREMEN DO A CURSORY INSPECTION OF THE TIRE; WE DECIDED IT WAS SAFE TO TAXI TO THE GATE. UPON INSPECTION WE FOUND THE TREAD FROM THE INBOARD R TIRE HAD SEPARATED. THERE WAS A DENT IN THE BOTTOM OF THE WING FROM DEBRIS IMPACT (ABOUT 6 INCHES LONG AND A COUPLE INCHES DEEP). THERE WERE SIGNS OF OTHER POTENTIAL IMPACT DAMAGE THAT THE MECHS WERE EVALUATING WHEN WE LEFT.
