Safety warnings!

I found this article a long time ago, I stumbled upon it again and thought I'd share it. Many of you may know that but some may not and you can't be too safe.

Plus, ever hear of this? Never apply heat to a wheel while the tire is on, it can explode. I can;t find the video of it but there are no signs that is is heating up. Just a really quick weld can cause this and the temp shoots up to over 1,000F and can even take 24 hours before it does this.

Wait, here's the video. This can happen even when the wheel is in the drop center, it builds up pressure fast enough that it can reseal the bead and blow up.

Hey, you can't be too safe. Well, yes you can but you get my point.
