Narrative:
I was the pilot monitoring. The flight was my ZZZZ saq so captain X was acting as my first officer. Captain X conducted the exterior inspection after we noted and discussed the yellow tire placard. The right nose tire was documented as worn and deferred. We noted 5 cycles/landings had been made since the write up. As this was my special airport qualification (saq); the brief was very extensive and referenced not only the typical documents but also the flight standards ZZZZ guide. The preflight and taxi out was normal. The single minor exception was a reroute upon initial contact with clearance delivery. We used the no engine bleed takeoff procedure in the handbook. During the takeoff roll I saw something hit the nose cone and heard a bang around the same time I was calling vr. At the time; I thought it may be a bird strike. When we raised the gear; I felt and heard significant vibrations of the nose gear. After safely clear from terrain and weather; we notified ATC of a possible blown tire and asked them to notify ZZZZ tower. We noted that all engine and pressurization indications were normal. We notified the company first via ACARS; then followed up by radio. All concurred to continue to ZZZ2. As the flight was scheduled for xa:44; we had ample time to review all appropriate procedures and checklists. We performed a gear down fly by at 1000 ft afe; then returned for a flaps 40 full stop. We experienced significant vibrations and noise during roll out with a tendency toward a right drift. We shut down; were inspected; and then towed to the gate.callback conversation with reporter revealed the following information: reporter confirmed they had declared an emergency prior to the flyby and landing and the aircraft was met by crash fire rescue equipment. Reporter discussed the incident with his air carrier safety department and his recommendation was that aircraft with deferred tire conditions not be dispatched to high density altitude airports.

Title: FLT CREW OF B737-800 EXPERIENCE NOSE TIRE BLOWOUT ON TKOF FROM A HIGH ALT ARPT. CONTINUE TO DEST AND LAND UNDER EMER CONDITIONS.
Narrative: I WAS THE PLT MONITORING. THE FLIGHT WAS MY ZZZZ SAQ SO CAPT X WAS ACTING AS MY FO. CAPT X CONDUCTED THE EXTERIOR INSPECTION AFTER WE NOTED AND DISCUSSED THE YELLOW TIRE PLACARD. THE RIGHT NOSE TIRE WAS DOCUMENTED AS WORN AND DEFERRED. WE NOTED 5 CYCLES/LANDINGS HAD BEEN MADE SINCE THE WRITE UP. AS THIS WAS MY SPECIAL ARPT QUALIFICATION (SAQ); THE BRIEF WAS VERY EXTENSIVE AND REFERENCED NOT ONLY THE TYPICAL DOCUMENTS BUT ALSO THE FLIGHT STANDARDS ZZZZ GUIDE. THE PREFLIGHT AND TAXI OUT WAS NORMAL. THE SINGLE MINOR EXCEPTION WAS A REROUTE UPON INITIAL CONTACT WITH CLEARANCE DELIVERY. WE USED THE NO ENGINE BLEED TAKEOFF PROCEDURE IN THE HANDBOOK. DURING THE TAKEOFF ROLL I SAW SOMETHING HIT THE NOSE CONE AND HEARD A BANG AROUND THE SAME TIME I WAS CALLING VR. AT THE TIME; I THOUGHT IT MAY BE A BIRD STRIKE. WHEN WE RAISED THE GEAR; I FELT AND HEARD SIGNIFICANT VIBRATIONS OF THE NOSE GEAR. AFTER SAFELY CLEAR FROM TERRAIN AND WEATHER; WE NOTIFIED ATC OF A POSSIBLE BLOWN TIRE AND ASKED THEM TO NOTIFY ZZZZ TOWER. WE NOTED THAT ALL ENGINE AND PRESSURIZATION INDICATIONS WERE NORMAL. WE NOTIFIED THE COMPANY FIRST VIA ACARS; THEN FOLLOWED UP BY RADIO. ALL CONCURRED TO CONTINUE TO ZZZ2. AS THE FLIGHT WAS SCHEDULED FOR XA:44; WE HAD AMPLE TIME TO REVIEW ALL APPROPRIATE PROCS AND CHKLISTS. WE PERFORMED A GEAR DOWN FLY BY AT 1000 FT AFE; THEN RETURNED FOR A FLAPS 40 FULL STOP. WE EXPERIENCED SIGNIFICANT VIBRATIONS AND NOISE DURING ROLL OUT WITH A TENDENCY TOWARD A RIGHT DRIFT. WE SHUT DOWN; WERE INSPECTED; AND THEN TOWED TO THE GATE.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR CONFIRMED THEY HAD DECLARED AN EMER PRIOR TO THE FLYBY AND LNDG AND THE ACFT WAS MET BY CFR. RPTR DISCUSSED THE INCIDENT WITH HIS ACR SAFETY DEPT AND HIS RECOMMENDATION WAS THAT ACFT WITH DEFERRED TIRE CONDITIONS NOT BE DISPATCHED TO HIGH DENSITY ALT ARPTS.
