This means that the tires used on commercial airplanes can last for 200-300 landings, which will be much less than the tires used on lighter aircraft. An airline can expect to get approximately 300 landings from the tires on an Airbus 380, which is the world’s largest passenger airliner.
How often are commercial airplane tires replaced?
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.
How long do jet airplane tires 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.
How much does a 737 tire cost?

Why plane tires do not explode on landing?
They’re like the tires on your car—but way stronger. 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.
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 do airplane tires not pop?
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.
How many tires does a 737 have?
The Boeing 737 Classic series and the Boeing 737NG series of airplanes both deploy two nose landing gear tires and four main landing gear tires. The Dunlop tire for the Boeing 737NG are designed to be robust and dependable; exactly what is needed for this workhorse of the skies.
How many tires does a 747 have?

Arguably the most popular single-engine general aviation aircraft, the Cessna 172 uses 6.00-6 tires on its main wheels and 5.00-5 on the nose wheel. Michelin offers the main wheel tires with a ply rating of 8 for approximately $235 and Goodyear offers the same for $237.
What is the most expensive part of an airplane?
The engine is one of the most expensive parts of an airplane. The engines used in large passenger airliners can cost many millions of dollars. For example, the 747-400 has three engine options ranging in price from $11 million to $12.2 million.
Why is nitrogen used in aircraft tires?
Aircraft Tire Inflation: When inflating aircraft tires, many regulatory agencies require nitrogen gas to be used. It provides a stable and inert atmosphere while also eliminating the presence of moisture within the tire’s cavity, preventing oxidative degradation of the rubber tires.
How much does a 747 tire weigh?
747-8 main tires weighs 270 lbs each. A fully assembled -8 wheel with hardware is close to 550 lbs! A Boeing 757 main tire weighs about 150 lbs. Main tires for an Embraer ERJ190 regional jet are about 145 lbs each.
Why are airplane tires so small?
The simple reason is that airliner tires are blown up to about 200 psi, or about six times the psi of a car tire, according to Wired. It is the high air pressure that gives airliner tires their strength. … This is much smaller than a semi-truck tire, which can be over 40 inches in diameter and almost 20 inches wide.
