User did not realize that letting go of the chuck would not stop air flow. The hose blew out, knocked him down and lifted the tire over a retaining wall. Severe head injury. The rim split in half and decapitated owner. Tell that to my knee.
Bike tires are thin-walled but also very small cross section.
Bicycle tires are bias ply, so the cords don't separate as the tire swells, like a radial. My tire engineer warns against exceeding sidewall rating by more than 10 percent. Orris says the first thing to fail should be the sidewall. Steel rims are formed from one piece of sheet and will not fail, but some aluminum rims might fail by the flange breaking off. The rim fragment will be a bullet.
