What is the first action to take when approaching an overheated tire?

When approaching an overheated tire, the best practice is to approach from fore or aft of the aircraft. This method is crucial for safety because it keeps you out of the potential line of failure if the tire were to blow out or rupture. By positioning yourself at the front or back of the aircraft, you reduce the risk of injury from any debris that might be expelled.

This approach is also grounded in understanding the dynamics of tire failure; overheated tires can fail violently, and the safest angles to observe and manage that risk are from the ends of the aircraft rather than the sides or directly above. Approaching from the side, above, or directly behind may place you in a more dangerous position where a tire failure could be more directly harmful to your safety. Thus, approaching from fore or aft is the most responsible and precautionary measure when dealing with overheated tires.
