Narrative:

Finished walkaround at XA45L. All tires showing 250 psi. Fans on #2; #3; and #4 tires. In cockpit tire temperatures 425+ degrees. On pushback; ground crew could not get chock out from under tire #3. Then they said #4 tire was flat. Supplemental information from acn 797838: all ready for pushback. Released brakes and started pushing back approximately 10 ft when tug driver advised us that 1 of our tires looked like it was flat. We requested to be brought back to the gate for closer inspection. Indeed tire #4 was going flat and we also discovered the #2 tire also going flat as well. Contacted maintenance and advised us that all tires would have to be replaced due to the stress put upon the remaining tires. Flight canceled. Not enough tires on hand. When we arrived at gate we spoke to inbound crew and they advised us that brakes got pretty hot and fans were brought. When we got in the cockpit we noticed brake temperatures above 450 degrees and that was 45 mins after flight landed. I don't think new flap procedure is a well thought out process.

Narrative: FINISHED WALKAROUND AT XA45L. ALL TIRES SHOWING 250 PSI. FANS ON #2; #3; AND #4 TIRES. IN COCKPIT TIRE TEMPS 425+ DEGS. ON PUSHBACK; GND CREW COULD NOT GET CHOCK OUT FROM UNDER TIRE #3. THEN THEY SAID #4 TIRE WAS FLAT. SUPPLEMENTAL INFO FROM ACN 797838: ALL READY FOR PUSHBACK. RELEASED BRAKES AND STARTED PUSHING BACK APPROX 10 FT WHEN TUG DRIVER ADVISED US THAT 1 OF OUR TIRES LOOKED LIKE IT WAS FLAT. WE REQUESTED TO BE BROUGHT BACK TO THE GATE FOR CLOSER INSPECTION. INDEED TIRE #4 WAS GOING FLAT AND WE ALSO DISCOVERED THE #2 TIRE ALSO GOING FLAT AS WELL. CONTACTED MAINT AND ADVISED US THAT ALL TIRES WOULD HAVE TO BE REPLACED DUE TO THE STRESS PUT UPON THE REMAINING TIRES. FLT CANCELED. NOT ENOUGH TIRES ON HAND.
