How can improper tire pressure affect landing gear performance?

Improper tire pressure significantly impacts landing gear performance, particularly in terms of stability during landings and the effectiveness of braking. When tire pressure is too low, tires can become deformed under load, which can lead to a lack of control during the landing phase. This can result in unstable landings, as the aircraft may not respond appropriately to pilot inputs due to variations in how the tires interact with the runway.

On the other hand, overinflated tires can lead to a harsher ride and reduced contact with the runway, which can also destabilize landings. Additionally, correct tire pressure is critical for optimal braking performance. When tires are under or over-inflated, the contact patch — the area of the tire that actually makes contact with the ground — is affected, which can diminish the effectiveness of the brakes. This can lead to longer stopping distances and increased risks during landing. Therefore, maintaining proper tire pressure is crucial for ensuring safe, stable landings and adequate braking performance.
