That rule came about due to the adventures in 1988 where they changed the
tire completely mid-year (I think it was shortly before nationals) from the
old street Comp T/A tread pattern (and I suspect carcass and everything) to
the 204/206-generation tires, with the assymetrical tread.  They still
called it the "Comp T/A R1".  Protests were filed, and after much gnashing
of teeth it was eventually determined that the way the rule was written (I
don't have the '88 rule book handy, sorry) that since they kept the same
name, it was legal.  I believe a consideration in that was that a finding
against the tire would hurt a large number of competitors.  This was the
first tire BFG had readily available to the masses which was really
competitive - a significant evolutionary change.  The situation in '89 was
that they kept the tread pattern, but changed compounding (REALLY hard to
enforce since when you get right down to it no two tires are EXACTLY the
same there, particularly if they are from different dates;  heck, the same
tire will be different AT different dates) and the carcass.  But you may
notice that they were smart enough NOT to designate it as "new".  So we had
rule which was not well written replaced by another rule which was not well
written.  I believe that after this, they spent some time talking to tire
people about how to write the rule....
