Narrative:

Shortly after takeoff we were advised by tower that the aircraft following us observed what appeared to be rubber tire pieces departing our gear on takeoff. They said they would inspect the runway and advise of their finding through a relay on the radio frequency we would be working. Lhr control shortly thereafter advised that; indeed; they did find tire rubber on the runway that came from our aircraft. We checked our gear synoptic and all other system synoptics and could determine no adverse indications from the tire failure. We checked with the flight attendants and none of them heard or sensed anything that would indicate that we blew a tire. We; subsequently; relayed the information to dd so they would be aware of the situation. Upon descent to ord we coordinated with dd to land on runway 4R because the winds were 220 degrees/21 KTS gusting 27 KTS and we would encounter very little crosswind on landing. We were informed by our mrd before departure that the #1 rear tire had some metal damage but was good for 8 more lndgs. Armed with this information and the fact we really did not know what exactly we were working with; as concerning the gear and tires; we elected to land on runway 4R to minimize the crosswind component and maximize the headwind factor for our landing. We requested that fire/rescue equipment observe our landing just in case an adverse situation should develop. Our flight attendants were informed and ready if any adverse situation should develop on landing; however; we told them it would most probably be a normal landing and taxi in. After landing; which was uneventful; the city inspector drove around our parked aircraft and informed us that all tires looked normal except the left aft on the left side; which was bald. We expect that we threw a retread on takeoff. We canceled the assistance of the trucks and received clearance to taxi to the gate.

Title: B777-200 SHEDS TREAD ON ONE TIRE ON TKOF. CONTINUES TO DESTINATION FOR UNEVENTFUL LANDING.

Narrative: SHORTLY AFTER TKOF WE WERE ADVISED BY TWR THAT THE ACFT FOLLOWING US OBSERVED WHAT APPEARED TO BE RUBBER TIRE PIECES DEPARTING OUR GEAR ON TKOF. THEY SAID THEY WOULD INSPECT THE RWY AND ADVISE OF THEIR FINDING THROUGH A RELAY ON THE RADIO FREQ WE WOULD BE WORKING. LHR CTL SHORTLY THEREAFTER ADVISED THAT; INDEED; THEY DID FIND TIRE RUBBER ON THE RWY THAT CAME FROM OUR ACFT. WE CHKED OUR GEAR SYNOPTIC AND ALL OTHER SYS SYNOPTICS AND COULD DETERMINE NO ADVERSE INDICATIONS FROM THE TIRE FAILURE. WE CHKED WITH THE FLT ATTENDANTS AND NONE OF THEM HEARD OR SENSED ANYTHING THAT WOULD INDICATE THAT WE BLEW A TIRE. WE; SUBSEQUENTLY; RELAYED THE INFO TO DD SO THEY WOULD BE AWARE OF THE SIT. UPON DSCNT TO ORD WE COORDINATED WITH DD TO LAND ON RWY 4R BECAUSE THE WINDS WERE 220 DEGS/21 KTS GUSTING 27 KTS AND WE WOULD ENCOUNTER VERY LITTLE XWIND ON LNDG. WE WERE INFORMED BY OUR MRD BEFORE DEP THAT THE #1 REAR TIRE HAD SOME METAL DAMAGE BUT WAS GOOD FOR 8 MORE LNDGS. ARMED WITH THIS INFO AND THE FACT WE REALLY DID NOT KNOW WHAT EXACTLY WE WERE WORKING WITH; AS CONCERNING THE GEAR AND TIRES; WE ELECTED TO LAND ON RWY 4R TO MINIMIZE THE XWIND COMPONENT AND MAXIMIZE THE HEADWIND FACTOR FOR OUR LNDG. WE REQUESTED THAT FIRE/RESCUE EQUIP OBSERVE OUR LNDG JUST IN CASE AN ADVERSE SIT SHOULD DEVELOP. OUR FLT ATTENDANTS WERE INFORMED AND READY IF ANY ADVERSE SIT SHOULD DEVELOP ON LNDG; HOWEVER; WE TOLD THEM IT WOULD MOST PROBABLY BE A NORMAL LNDG AND TAXI IN. AFTER LNDG; WHICH WAS UNEVENTFUL; THE CITY INSPECTOR DROVE AROUND OUR PARKED ACFT AND INFORMED US THAT ALL TIRES LOOKED NORMAL EXCEPT THE L AFT ON THE L SIDE; WHICH WAS BALD. WE EXPECT THAT WE THREW A RETREAD ON TKOF. WE CANCELED THE ASSISTANCE OF THE TRUCKS AND RECEIVED CLRNC TO TAXI TO THE GATE.
