Airplane Tires Donâ€™t Explode on Landing Because They Are Pumped!

Aircraft tires are amazing when you think about it.Â
The typical airliner tire can handle a 38-ton load. It can meet the groundÂ 500 times before needing a re-tread, a refresh it can take on seven times in its life.
A Boeing 777 uses 14 tires, Airbusâ€™ A380 carries 22, and theÂ enormous Antonov An-225Â demands 32. The key to their remarkable durability is maximizing the air pressure, says Lee Bartholomew, lead test engineer for Michelin Aircraft Tires. The high-flying rubber is typically inflated to 200 psi, roughly six times what you put in an automobile tire, and the tires on an F-16 fighter are pumped to 320 psi.Â Â â€śItâ€™s really pressurized air thatâ€™s so strong,â€ť he says.
