What's amazing about wheels is, how much weight and the force of impact they take when they hit the ground. Besides engines, wheels are up there of importance, but they get less appreciation.
I spent 19 years on that beast; 2 as a Crew Chief and the remaining as a Flight Engineer. Never got to crew the “M” though. She’s a magnificent bird.
Those tires are huge & 200 PSI. It took 2 of us to change a tire. I was a communication/navigation technician in the Air Force Reserves & since that equipment didn't often break I usually helped out with tire changes, etc.
It really doesn't need the 28 wheels to support the aircraft. There was a requirement in design for operation off of unimproved airports. I believe it was tested but never really used. A 747 weighs in at nearly 1,000,000 LBs and it has less wheels.
