Re: Tire size and Antilock Breaking Systems (fwd)
Dean Dardwin posts a lot on rec.autos.tech. Occasionally he's right
about stuff, often he's wrong, but he's always convinced of his correctness
and is abusive to people who disagree.
He's really outdone himself with this, though...

Bob,
You are a liar and a fool.
Google bought USENET.
There is no need for you to repeatedly post your nonsense here, we
already know you are a fool as well.
