The four major manufacturers in aircraft tire manufacturing are the following according to a report by Pelmar Engineering in 2013: Goodyear (United States) Michelin (France) Dunlop Aircraft Tyres (United Kingdom)
What tires do airplanes use?
A Boeing 777 uses 14 tires, Airbus’ A380 carries 22, and the enormous Antonov An-225 demands 32. The key to their remarkable durability is maximizing the air pressure, says Lee Bartholomew, lead test engineer for Michelin Aircraft Tires.
Does Goodyear make airplane tires?
In 2009, Goodyear is the world’s largest supplier of aviation tires for commercial, military and general aviation aircraft. Operating a global business from its Akron, Ohio headquarters, Goodyear manufactures aviation tires and retreads in the United States, Thailand, Brazil, and The Netherlands.
How much does a airplane tire cost?
All airplane tires are sold in sizes that are directly related to the size of the aircraft they are to be used on. But on average, the cost of an aircraft tire can range from $15 to $5500.
What are airplane tires made of?
Airplane tires are very different from car, truck or bicycle tires. In fact, airplane tires have about as much in common with these tires as they do with running shoes! They are all made of rubber. They all contain air.
How long does an airplane tire last?
Some recapped tires will last for up to 100 landings, while others will need replacement far sooner. The tires on an Airbus 380 jet will last for approximately 300 landings, which is approximately six months of operations.
Are airplane tires filled with water?
Aircraft tires generally operate at high pressures, up to 200 psi (14 bar; 1,400 kPa) for airliners, and even higher for business jets. … During the tests the tires have to be filled with water, to prevent the test room being blown apart by the energy that would be released by a gas when the tire bursts.
Who owns Goodyear?
The Goodyear Tire & Rubber Company is an American multinational tire manufacturing company founded in 1898 by Frank Seiberling and based in Akron, Ohio.

What size are airplane tires?
Airliner tires aren’t particularly large—the Boeing 737 tires measure 27×7. 75 R15, which means they are 27 inches in diameter, 7.75 inches wide, and they are placed on a 15-inch rim. This is much smaller than a semi-truck tire, which can be over 40 inches in diameter and almost 20 inches wide.
How do you read airplane tire sizes?
The first numbers in the tire spec represent the size of the tire. For example, in a 6.00×6 tire the “6.00” indicates the nominal width of the tire, while the “6” indicates the diameter of the wheel that the tire is designed to fit. General aviation tires utilize bias-ply construction (vs. radial).
What is the most expensive part of a plane?
For a commercial airliner the cost of the engines is in the ballpark of 15–20% of the fly away cost. Probably making it the single most expensive component.
What is the cheapest commercial airplane?
The Boeing 737-700, listed at an average price of just under 90 million U.S. dollars, is among the least expensive models, while the Boeing 777-9, priced at 442 million U.S. dollars, is among the most expensive ones on Boeing’s price list.
How much do 747 pilots make?
Pilots of 747s earn between $25,000 and $200,000, depending on experience and the employers for which they work, according to the AVScholars website, a career website for aviation professionals.
Do airplane tires spin before landing?
Immediately when an aircraft touches down, the tires are actually skidding, not rotating. In the seconds that follow, the velocity of the plane is transmitted gradually to its tires until the tire’s rotational speed matches the plane’s velocity.
Why do airplane tires smoke on landing?
Answer: The smoke is the result of a wheel which is not turning in flight making contact with a stationary runway. The wheel must accelerate to the landing speed very quickly. During that acceleration, there is a short time when the tire is skidding, which produces the smoke.
How often do planes change 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.
