Sorry to send this to the entire list, but I can't seem to get thru to Fletcher

Fletch,

The tire treadwear indicator (280 or what ever) means that the tire will wear
like 2.8 times the treadwear of a tire rated at 100.  Everything is related to
100, therefore, all other conditions being equal, (air pressure, driving
habits, roads, etc.) a tire rated at 400 will wear four times as long as a tire
rated at 100.  Confused yet? -- Good!!   Cause now it really gets fun.
Traction and temperature is rated A-C, I don't think it gets to D and I
wouldn't want to drive on them anyway!! As you can guess, "A" is best and "C"
is worst.  Traction is the amount of traction a tire has on WET pavement,
STOPPING in a straight line.  Doesn't relate to dry pavement or cornering
ability at all.  That's why they make Autox, so you can find out about that
kind of traction.  ;>)

Temperature is fairly self explanatory, again "A" is best, here in sunny
Hooootttt Arizona, I wouldn't run a tire that wasn't an "A" rating for
temperature.  If fact if I could find an A++, I'd probably be using them.

I hope I didn't confuse you too much, any questions, get back to me.
