Narrative:

I was PIC flying as copilot for a type rating chkride in CE750. Aircraft landed and back taxied to hold for another takeoff. We needed a delay so taxied off runway and held short of another parallel runway. When cleared for takeoff; the aircraft rode roughly as we pulled forward. We stopped and opened door to find left hand outboard main tire flat and smoking. I advised tower. After a minute or two; the tire smoked more and then burst in flames. I declared an emergency with tower; requested equipment; shut down the aircraft and evacuated everyone from the aircraft. PF in left seat; me; designated examiner and FAA inspector. We waited as the second main also caught fire before the trucks arrived and put everything out. Ambient temperature at the time was around 110 degrees fahrenheit.
