Danger, Danger, Personal Opinions follow, once again. Burn before reading,
hit you delete key now!

Nope, rolling resistance is not, in my opinion an "Aero Function". It is a
speed function and load function. The charts I have clearly show that it is
not linear however, it does become more linear as speed goes up. All of the
things you mention about air around the tire and management of the air are
"Aero Functions". You could have a perferct air management system and still
have high rolling resistance (ala the deflated tire example). As speed
increases the effect of air pressure inside the tire lessens, because of
centrifugal force on the tread surface and the contact patch gets smaller,
IMHO. Remember, I am only stating my opinions and if you got better info,
then by all means, use it! I do think that rolling resistance is one of the
great uknowns in LSR. The perfect tore would be a solid aluminum one because
it does not flex. A lessor component to rolling resistance is the surface on
which it is rolling. The last couple of years the salt has been pretty hard
and IN MY OPINION does not contribute much to rolling resistance. It does
get slippery when some of the surface disintegrates and the surface then
becomes like a shuffle board game's surface.

If you have read this far, you are contaminated  by my personal opinions and
may suffer greately through ridicule from you compatriots!

Oh, does anyone know where I can get a copy of "Tire Rolling Resistance" .
Long out of print, but I tired to order one from Amazon.com...no luck.
Anybody seen a copy in a library?

mayf, the very red necked ignorant desert rat in a cold and very windy
Pahrump who may have carpets in the hew house by next friday but I an't
holding my breath...
