RE: Any Tire Dopers out there?

        Can't speak for DOT tires, but the stuff I've tried works on
slicks. I've used 2 diff types and they both prolong the life of the tire.
They DO NOT make it any softer than it was originally. I use it as 
a money saving product to extend the number of decent runs I get
from a set. I don't inhale :-)
