Which condition is likely caused by tire under-inflation?

Tire under-inflation can lead to several detrimental effects, with premature tire failure due to heat damage being a prominent concern. When a tire is under-inflated, increased flexing occurs as the tire rolls, which generates more heat. This excessive heat can cause the tire materials to degrade more rapidly, ultimately leading to premature failure.

Heat build-up affects the structural integrity of the tire, and over time, can cause issues such as tread separation or blowouts. Maintaining proper inflation levels is crucial for ensuring tires operate within safe temperature ranges, thereby prolonging their operational lifespan and maintaining safety during flight.

In contrast, decreased tread wear across the surface would typically occur with proper inflation levels, as the tire would wear evenly. Increased fuel efficiency is associated with maintaining the correct tire pressure, as under-inflated tires increase rolling resistance, which can actually decrease fuel efficiency. Improved aircraft handling also benefits from optimal tire inflation, as under-inflation can negatively impact the stability and control of the aircraft during takeoff, landing, and ground operations.
