The 200 treadwear rating on the Azenis proves how much of a joke the rating
system is. They're wearing much faster than my Michelin Pilot Sports (160?)
they replaced, and provide a lot more grip.
Maybe we should have an exclusion list for Street Tire instead (although
keeping it up to date would be difficult)

The other 2 new tires that will surely factor in next years street tire
classes are the Falken Azenis and Kumho ECSTA MX. Falken was sneaky enough
to give the Azenis a 200 treadwear rating, but the ECSTA MX is still listed
as "TBD". These tires are both very cheap and cater to the STS/STX crowd,
to the point where they actually mention the SCCA in their advertising.

I am not aware of any tires with a treadwear rating of 120 or 130.
The lowest treadwear tires I know of other than "R" tires have a
rating of 140. They include:
Bridgestone RE71, S-02
Pirelli PZero
Michelin Pilot SX MXX3
I noticed that the Z06 Corvette comes with a Goodyear tire model which
is not listed on Goodyear's web site. I wonder if there might have
been cases in the past where unique original-equipment tire models
have treadwear ratings below 140.
STX is a new street tire class with rules between STS and SM. STR is
being dropped.
