B737-300 OUTBOARD MAIN TIRE GOES FLAT AFTER FLC REJECTS TKOF DUE TO WINDSHEAR ADVISORY.

Narrative

AFTER WAITING FOR 2 MICROBURST ALERTS TO CLR ON RWY 25 AT DENVER AND AFTER 20-30 MINS ELAPSED TIME; WE MADE A DECISION TO TAKE OFF; SINCE THE WINDS HAD GONE TO STEADY STATE OUT OF THE NW. MAX PWR BLEEDS OFF WAS USED AND WINDSHEAR RECOVERY PROCS DISCUSSED PRIOR TO TAKING THE RWY. APCHING 120 KTS; THE TWR RPTED A 25 KT LOSS ON OUR RWY AND I MADE THE DECISION TO ABORT AT ABOUT 125 KTS. REMAINING RWY WAS APPROX 7000 FT AND COMPUTED V1 WAS 141 KTS. A PUFF OF SMOKE WAS RPTED COMING FROM OUR L MAIN GEAR; SO WE ASKED FOR FIRE TRUCKS TO MEET US. REJECTED TKOF BRAKING WAS DISABLED ALMOST AS SOON AS IT CAME ON AS THERE WAS PLENTY OF RWY REMAINING. WE ASKED THE AFT FLT ATTENDANT TO CHK FOR SMOKE FROM L MAIN GEAR AND SHE RPTED IN THE NEGATIVE. ALSO; THE FIRE DEPT PERSONNEL VERIFIED THIS. MAINT AND DISPATCH WERE CONTACTED AND IT WAS DETERMINED THAT NO INSPECTION WAS REQUIRED SINCE REJECTED TKOF HAD BEEN DISABLED AT 110 KTS. WE COORD WITH DISPATCH AND DECIDED TO TAKE OFF AFTER 30 MINS WAIT. HOWEVER; WHILE WAITING FOR TKOF; AN ARPT OPS PERSON OBSERVED OUR OUTBOARD L MAIN TIRE GO FLAT. MECHS WERE CALLED TO CHANGE TIRE WHILE CREW AND PAX EXITED THE PLANE ON TXWY VIA AIRSTAIRS. ANOTHER PLANE WAS FOUND AND WE DEPARTED DEN FOR ZZZ. MY DECISION TO ABORT WAS INFLUENCED BY THE 2 PREVIOUS WINDSHEARS; LESS THAN V1; AND RWY REMAINING.
