According to a Huffington Post story, when the fire extinguisher doesn't hack it, there's always some brewskis that will do the trick.

A Houston firefighter, Craig Moreau, saw this 18-wheeler on the side of the road with smoke billowing out of a tire.  I guess Mr. Moreau tried to use a fire extinguisher on board but it didn't work.  So guess what they used.Check it out!

I would never have thought that it would work.  Amazing.  Usually I would say that was a senseless waste of beer, but not in this case.  Congrats to Craig and Coors!!
