You take a Lincoln head penny and stick him head first into the tread, 
see how far
it goes in.  Turns out the distance between the edge of the coin and the 
top of his
hair is real close to the minimum tread depth recommended, so if any of 
his hair
is below the surface of the tire the tread is still okay.
