Can an aircraft owner change a tire?

Most aircraft maintenance tasks are the domain of licensed A&P mechanics. However, with the proper training and tools, changing a tire is something any aircraft owner or operator can do. However, it’s important to note that dealing with tires can be extremely dangerous if not done correctly.

Are airplane tires filled with water?

When landing, the strong friction of the runway and the brakes creates a very high temperature in the aircraft tires. The tires are filled with nitrogen to prevent fires from the extreme heat. But there is another reason for the N2 filling. Air contains water due to the humidity.

What is the tire pressure on a Boeing 767?

Large aircraft tire pressures are ridiculously high. A Boeing 767-300 main wheel is inflated to 205 psi. The high pressure supports the tire’s maximum rated load of 51,000 lbs. Aircraft wheels incorporate safety devices to protect the aircraft and personnel working nearby.

Do airplane tires need regulators to inflate?

Though many wheels include overinflation pressure relief valves to prevent the buildup of excessive pressure in the wheel/tire assembly, a regulator should always be used when inflating tires. Thousands of airplane tires are inflated during routine maintenance each day around the world.
