What is the recommended tire pressure for the main wheels?

The recommended tire pressure for the main wheels is typically predetermined by the aircraft manufacturer and is crucial for safe operation and performance. A tire pressure of 38 PSI is commonly suitable because it provides the appropriate balance between load capacity and stability. Maintaining this pressure helps ensure optimal performance during takeoff, landing, and ground handling, thereby enhancing safety and improving the overall handling characteristics of the aircraft.

It's also important to consider that tire pressures that are too low can lead to poor handling and increased wear, while excessively high pressure can result in decreased traction and a harsher ride. Therefore, adhering to the manufacturer's recommended pressure is essential for the best operational performance and the longevity of the tires.
