A Mg fire is notoriously hard to put out,
Can you even put one out?
As I recall the stuff can spontaneously combust in water.

Oh nooo (in my best Mr. Bill voice). What happens when you try to wash them, huh? I think someone is confusing metallic Sodium with Magnesium. Years ago, I had real Magnesium wheels on the front of my 67 Caprice Jr. stocker. Even though they were classified as lightweight wheels and may not have been technically legal, a can of black paint camouflaged them. I even had several tech inspectors comment on how ugly the wheels were. Little did they know how light they were.
