Narrative:
When cleared onto the runway, we heard a slight noise and vibration. I felt some movement in the tiller and assumed we slipped on a flush mounted light. Everything appeared normal and we continued the takeoff. After rotation, the tower informed us that we had blown a tire. After further discussion, we confirmed which tire. We discussed with dispatch and maintenance and decided the safest course was to continue to rjaa and land with a lower gross weight. A normal approach and landing was made at rjaa. Supplemental information from can 627368: in the climb out, sfo tower notified us that we had a blown tire on the left outboard forward wheel. Subsequent inspection showed that the tire in question was blown but intact on the rim, it had just been installed on aug/fri/04, and I believe we were the first flight on that tire as the aircraft had just come out of maintenance.

Title: B747-400 EXPERIENCES TIRE FAILURE AT START OF TKOF ROLL AT SFO BUT LEARN OF IT AFTER AIRBORNE. CONTINUE TO DEST AND LAND SAFELY.
Narrative: WHEN CLRED ONTO THE RWY, WE HEARD A SLIGHT NOISE AND VIBRATION. I FELT SOME MOVEMENT IN THE TILLER AND ASSUMED WE SLIPPED ON A FLUSH MOUNTED LIGHT. EVERYTHING APPEARED NORMAL AND WE CONTINUED THE TKOF. AFTER ROTATION, THE TWR INFORMED US THAT WE HAD BLOWN A TIRE. AFTER FURTHER DISCUSSION, WE CONFIRMED WHICH TIRE. WE DISCUSSED WITH DISPATCH AND MAINT AND DECIDED THE SAFEST COURSE WAS TO CONTINUE TO RJAA AND LAND WITH A LOWER GROSS WT. A NORMAL APCH AND LNDG WAS MADE AT RJAA. SUPPLEMENTAL INFO FROM CAN 627368: IN THE CLBOUT, SFO TWR NOTIFIED US THAT WE HAD A BLOWN TIRE ON THE L OUTBOARD FORWARD WHEEL. SUBSEQUENT INSPECTION SHOWED THAT THE TIRE IN QUESTION WAS BLOWN BUT INTACT ON THE RIM, IT HAD JUST BEEN INSTALLED ON AUG/FRI/04, AND I BELIEVE WE WERE THE FIRST FLT ON THAT TIRE AS THE ACFT HAD JUST COME OUT OF MAINT.
