When in doubt, delay, if possible, the gear retraction due to the possibility of a landing gear fire. Back in July of 1991 Nigeria Airways Flight 2120 (operated by Canadian company, Nationair) crashed soon after departure from Jeddah, Saudi Arabia, killing all 261 people aboard. Under-inflated main gear tires overheated, failed and caught fire during the takeoff run. The burning gear was retracted into the wheel wells, eventually melting structure and penetrating a fuel tank.
