Busrt tire/tires on takeoff roll? What can cause overheated tires after the long taxi to 7R? Slow taxi, which includes lots of braking? Heavy weight can exasperate. Is this the price of no block guarantee pay by cx which isn't done by any airline we've heard of? Was it worth the price cx?
After an RTO (even starting with dead cold brakes) brakes will always overheat on a heavy aircraft. Let alone after a long taxi to begin with. Temperature begins to rise at a rapid rate resulting in tire deflation. After that the brakes will catch fire. They certainly will smoke a lot. Very thick smoke. Fire crews observing will almost always call out brake fires. If you're at the gate and there's no jetbridge driver, you have no choice but to evacuate having been told the word "fire".
Best strategy is to stop the aircraft and have fire crews get in position for the inevitable brake fires. Not to put an aircraft which has a chance of burning down in a fire with a full load of fuel right up to a terminal building.
Who decides its OK to taxi an aircraft with less than all its tires anyway?
All in hindsight. FWIW
