What are airplane tires worth?
Each tire is worth about $5,000. Aircraft tires generally operate at high pressures, up to 200 psi (14 bar; 1,400 kPa) for airliners, and even higher for business jets.
What kind of tires are used on airplanes?
75 R15 rubber. In English, that means it is 27 inches in diameter, 7.75 inches wide, and wrapped around a 15-inch wheel. The sidewalls aren’t terribly thick, and the strength of the tire lies in the cords embedded below the tread, Bartholomew says. They’re typically nylon, and more recently a variety known as aramid.
What is the shelf life of aircraft tires?
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.
What company makes the most airplane tires?
Goodyear is the largest producer of aircraft tires, followed closely by Michelin, Dunlop and Bridgestone, according to Peled.
How much does a 737 tire cost?
around $1,500 each
A Boeing 737 main tire, of which there are four per aircraft, costs around $1,500 each, Mowry said, explaining that manufacturers can re-tread these tires up to three or four times to extend their lifetime.
How much does an Airbus A380 tire cost?
At $5000 a pop, an A380 tyre isn’t cheap and each wheel on the main landing gear weighs almost 120 kilograms.
Why do plane tires don’t explode on landing?
The mechanics take off the hubcap and reduce the tire pressure from 200 to 30 psi, which reduces the risk of it exploding as the bolts and nuts holding it on the plane are removed. A sleeve protects the axle, and a lifting tool pulls the tire off. The axle sleeve is then greased, and the new tire is slid smoothly on.
When should airplane tires be replaced?
The tire should be replaced when tread has worn to the base of any groove at any spot or to a minimum depth specified in the aircraft maintenance manual. Tread wear can also be an indication of improper tire inflation.
Why 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.
How often do plane tires get changed?
every 120 to 400 landings
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.
