AN MD80 CREW HEARD A LOUD SOUND COME FROM NOSE GEAR. SUSPECTED TIRE FAILURE. EMER DECLARED. FOUND TREAD THROWN FROM L NOSE TIRE.

Narrative

COMMENCED A NORMAL TKOF ROLL AT MCI RWY 19R. AT ROTATE WE HEARD AN EXTRA LOUD SOUND FROM THE NOSE TIRE AREA. IT SOUNDED LIKE WE WERE HITTING RATHER LARGE CTRLINE LIGHTS. ONCE AIRBORNE; NOISE IMMEDIATELY WENT AWAY. I CALLED MCI TWR AND ASKED IF THEY HAD OTHER COMPLAINTS ABOUT THE 'ROUGH RWY.' THEY SAID I WAS THE FIRST. DISCUSSED WITH FO WHAT ELSE THAT NOISE COULD BE. THOUGH NEITHER OF US HAD EVER EXPERIENCED A TIRE FAILURE BEFORE; WE GUESSED THAT COULD BE THE PROB. I THEN RELAYED THROUGH THE COMPANY OPS TO HAVE MCI ARPT OPS CHK OUT THE RWY FOR ANY RUBBER FOREIGN OBJECT DAMAGE. ABOUT 10 MINS LATER THEY PASSED ON TO ME THAT THEY DID IN FACT FIND RUBBER STRIPS AT THE ROTATE AREA. WE BROKE OUT THE SUSPECTED TIRE FAILURE PROCS AND DECIDED TO BURN DOWN THE FUEL BY CONTINUING ON TO DFW. I THEN DECLARED AN EMER AND STATED OUR INTENTION TO LAND AT DFW AND STOP ON THE RWY UNTIL CFR AND MAINT COULD CHK US OUT. I THEN COORDINATED WITH DISPATCH ABOUT OUR PROB. I BRIEFED THE FLT ATTENDANTS AND PAX. WX AT DFW WAS VMC. I BRIEFED THE APCH AND LNDG CONSIDERATIONS; AND PROCEEDED TO MAKE AN UNEVENTFUL LNDG ON RWY 17R. WE STOPPED ON THE RWY AND BOTH CFR AND COMPANY MAINT CHKED US OUT. THEY FOUND THE L NOSE TIRE TREAD HAD SEPARATED YET THE TIRE ITSELF MAINTAINED NORMAL TIRE PRESSURE. THEY GAVE ME THE OK TO TAXI TO THE GATE WHERE A NORMAL TIRE CHANGE WOULD TAKE PLACE.
