Right. The airplane tires go from being 50 degrees below zero while the plane is cruising up to about 300-400 degrees when the plane lands.

Takeoff speed is lower than landing speed. The more important element is the weight of the aircraft. That is why airplanes jetison fuel if they have to turn around and land after takeoff. It's also the reason the pilot takes on a specified amount of fuel at each stop. They want to land the aircraft as light as possible to save wear and tear. This test simulates a jet fully laden with fuel that has to make a stop on the runway.

To answer your question about aircraft tires keep in mind there is a BIG difference from automotive and aircraft tires. Nitrogen is a dryer, more stable gas that's less prone to changes in pressure due to heat or cold. Nitrogen will not degrade the interior rubber of the tire or corrode the wheels, since it contains no oxygen or water vapor both present in the atmosphere. You should understand all aircraft tires leak nitrogen

Overweight landings are the same as a rejected takeoff I believe. The test is preformed at the maximum takeoff weight of the aircraft, at the takeoff speed (which is faster than the landing speed), and without the help of the thrust reversers. This simulates a worst case scenario in which there is a failure in the engines and the brakes must stop the aircraft without any help from the reversers. Under normal conditions the reversers account for 50% of the braking power.

if you ask for my opinion it wouldent be that bad beacous you have a bunch of wheels instead of one and you have reverse thrush + speed breaks so it probley wouldent be that bad

Very good video

oh my shit 125 MJ?? is that right?? on the other video here of a 777 doing an aborted take off they state it dissipated 9.7 million ft-lbs of energy which is only like 13 MJ and that's a whole plane on MANY wheels. why would a single wheel ever have to dissipate 125 MJ?
