<P><<<<<Yo Chi-town,

<BR>If you know the answers what the hell are you asking me the questions

for! <grin>

<BR>Seriously, it is everything you mentioned, (speed, balance, etc) and

I also want to stay with a 15" race tire/wheel

<BR>combination on the Pantera. The Winston cup tires are pretty damn durable

and hold up well to

<BR>the speeds run at Silver State.  When I made the decision to move

up in speed I spoke to Bobby Byers,

<BR>and Junior Wilson again who have run the high end speeds and they both

endorsed the race tires. They both believe

<BR>the Winston Cup tires are better suited for the high end stuff. . .I

have alot of respect for these guys because they have as Go-Nancy so aptly

put it, <B>"been there - done that!"  Don't get me wrong - I'm

totally open to data or input that will support otherwise.



<P>FWIW, I think "any" of the DOT Z-rated legal performance tires out there

(Yoko's, Pirelli, Hoosier, BFG, etc) will get the job done up to 170mph

but all these DOT legal tires have also experienced some tire failure and/or

tire tread seperation on the high-end at speeds at or above 170 mph in

this event on heavy vehicles.   I ran new BFG R-1's in each of

the last two SS events on stock Campy rims (7&8's) and they performed

great. I think their good tires.  And I wouldn't hesitate to run them

again - at speeds up to 170mph.

<BR>MD
