How many of you guys remember Charlie Gibson?  He was one hell of a racer, and 
also a partner in SASCO MOTORSPORTS (Racing Tires).  He was killed in a 
regrettable work place accident when he was returning one of the big SASCO 
semi-trailer rigs from an event, to their shop at VIR.  He was all alone, and 
there was a 'brake issue.  When he disconnected the trailer, it rolled back 
over on him and killed him.  SAD, Sad, sad!  But I bring him up because back in 
the 1980s he was an avid vintage racer, and always brought a race car with him, 
which he raced at events he sold tires at.  Anyway, racing tires was his 
business. Super nice guy.  Like all of us, he had opinions, and he shared them. 
 He said vintage race cars ought to be racing on tall, skinny tires.  He did 
not seem to be hung up on compounds.  His hang up was profile.  He said our 
cars should not run tires less than 70 profile. The VSCDA agreed with that, and 
for our group...your tires had to be no less than 70 profile.  I can't remember 
if there was a list of approved tires, but I do know Dunlop "Gumballs" were a 
no-no.  They were made for a while, were almost as sticky as they were 
expensive.  Early on...I had heard about them...but could not afford them.  
Pity.  Dunlop tires look SUPER on a TR.

If you watch enough Goodwood Revival race videos, you realize they are running 
on the skinniest tires and probably hardest compound and they put on quite a 
show.  But the race organizer demands period correct!Charly MitchelTR6 #44On
