What is the function of tire pressure gauges during a Daily Inspection?

The function of tire pressure gauges during a Daily Inspection is to ensure that the tires are adequately inflated for safety. Maintaining the proper tire pressure is crucial for the safe operation of the aircraft, as under-inflated or over-inflated tires can significantly impair the aircraft's performance, handling, and operational safety.

Adequate tire pressure helps ensure optimal contact with the runway, improving traction and reducing the likelihood of tire blowouts or failures during critical phases of flight such as takeoff and landing. It also contributes to even wear on the tires, which can extend their lifespan and enhance performance. Inspecting and verifying tire pressure as part of daily inspections is a vital safety measure that the Plane Captain must emphasize to ensure readiness and safety of the aircraft.

In this context, while other choices discuss related tire concerns, they do not fully capture this essential safety aspect as effectively as the correct choice does.
