Do aircraft tires have a shelf life?
Tyres can be inflated at operational pressure if allowed by the aviation authorities. The assemblies can be stored like this for up to 12 months. After that time, inflated assemblies that have not been used should be re-inspected to tyre appearance criteria.
How often do planes get new tires?
Tires are changed every 120 to 400 landings depending on a number of factors. Aircraft tires need to withstand an extremely wide range of temperatures that go from minus 60 degrees Celsius at an altitude of 10,000 meters to extremely high temperatures when landing in the world’s hottest regions.
What is the average life of aircraft TYRE?
The typical airliner tire can handle a 38-ton load. It can meet the ground 500 times before needing a re-tread, a refresh it can take on seven times in its life. A Boeing 777 uses 14 tires, Airbus’ A380 carries 22, and the enormous Antonov An-225 demands 32.
Where are the wear limitations of a tire found for aircraft?
This limit is when the wear level reaches the bottom of any tread groove along more than one-eighth of the circumference on any part of the tread, or the tread-reinforcing ply of a bias- ply tire or the protector ply of a radial tire is exposed for more than one-eighth of the circumfer- ence at a given location.
Are airplane tires filled with nitrogen?
Aircraft tires indeed are filled with nitrogen to mitigate temperature fluctuations, but not because nitrogen has any special heat-absorbing qualities. Rather, it’s the presence of water that makes standard, commercially available compressed air a poor, even dangerous choice for aircraft tires.
What is the greatest enemy of an aircraft tire?
Brown tells us heat is the aircraft tires most potent natural enemy; anticipating and managing the heat generated in operation is one of the tire designers key objectives.
