apologies in advance...

["R. W. Zehr" <rzehr@pacbell.net>]

With apologies to Ogden Nash, perhaps the following can help avoid a
lengthy speculative thread on tire engineering and design.

After reading, everyone please groan deeply, and refrain from
responding...

It's the coefficient of friction,
(a mathematical fiction).
that determines when a tire begins to skid,

And ignoring snow and water,
the tread shape shouldn't ought'er,
influence what the tire ever did.

It's material that matters,
while your tire pitter-patters,
over all those tiny bumps upon the road,

And the contact patch depends,
on the weight and tire pressure,
that in turn sets the parameters of the load.

Sorry,
Rick Zehr  ;>)
