I've seen some catch fire in a video after a car wrecked. Like roadsterdoc said before, the wheel contacting the ground, I would think, could start a fire.

EDIT: I really gotta start looking at the age of the thread first, haha.

Lots of misinformation, even though this is a resurrect...

Solid magnesium won't combust unless we're talking about a nuclear explosion.
No, having a magnesium wheel scrap asphalt will not cause it to ignite.
Sure, the magnesium dust coming off the wheel will produce some spectacular fireworks...

Second, the "myth" about magnesium oxidizing is pretty much false.
Earlier magnesium parts had this problem that was eventually traced to impurities in the castings.
Modern production of magnesium parts have basically gotten rid of this impurity problem, and oxidation is not a factor.
Unless we're talking about some cheap-*** Made-in-China part, good quality magnesium components should not be eroding away in your driveway.

^I probably won't be able to find the video now anymore, but I DID see the wheel catch on fire. It may not have been a magnesium wheel, but I don't know of any others that have been said to catch fire, haha. And I'm not sure what made it catch fire, I just know what I saw.

 

Do you happen to know what kinda car and about how old those wheels were?
Some of the older stuff could've done that due to impurities.
All the good quality mag stuff over the part 10 years should not do this...

^actually I don't know how old the car was, I think it was a fairly recent video though. I actually watched it again a little bit ago, it was a rally car and it didn't look like the tire even blew. I don't remember what website I got it from, I'll try to find it when I get off work. All I have is the video saved to jumpdrive.
