What are the primary contributors to the wear of aircraft wheels?

The primary contributors to the wear of aircraft wheels involve a combination of several factors, making the chosen answer the most comprehensive. High tire pressures can lead to uneven wear patterns, affecting the integrity of the wheels over time. Cyclic loading, which occurs as the aircraft takes off and lands, exerts repetitive stress on the wheels, contributing to metal fatigue and wear. Corrosion can occur due to exposure to environmental elements, such as moisture and various chemicals, which can deteriorate the material of the wheels, reducing their lifespan and effectiveness. Additionally, physical damage from foreign objects on runways or during maintenance can compromise the structural integrity of the wheels.

This multifaceted approach highlights that wear on aircraft wheels cannot be attributed to a single factor; instead, it results from an interplay of high tire pressures, cyclic loading, corrosion, and physical damage, making the answer the most accurate representation of the wear mechanisms at play.
