I used to sell split rims in the '70s. They were no more dangerous
than one-piece rims if they were used properly, and there was the
catch: they weren't idiot-proof. There are many non-interchangeable
styles of side and lock rings, and stupid people would mix them up and
blow themselves to bits when the thing came apart. A 10.00-22
wheel/tire at 110 psi has enough energy to send a 160-pound man 600
feet into the air. Theoretically. In reality, his body parts are spread
over a similar area. So the wheel companies had to get away from those
things and tires are now much harder to change without the expensive
equipment.
But what can you do with people who insist on wrecking perfectly
good airplanes using bad judgement and then blaming, $ucce$$fully, the
manufacturer, and making flying so unnecessarily expensive for the rest
of us? Stop building airplanes?
