The part that is of particular interest to us Yaris pilots:

STREET TOURING

• The previously-published proposal to revise the ST category minimum treadwear rating has been withdrawn. The SEB
  believes at this time that a better way to address specific parity issues is to make use of the ST exclusion list.

• The SEB is considering, per 14.3.D, the following addition to the ST tire exclusion list, effective 1/1/2013:
  

  Toyo Proxes R1R 195/50-15 size only

  Comment: This size has proven to be faster than the rest of the R1R lineup, and in classes in which some cars can use this tire where other cars cannot, it is discouraging participation by those unable to use it. It is the opinion of the SEB that those members who are currently running this tire have many other options which will maintain the competitiveness of their car,
  while also encouraging more participation by those members who cannot use this size. Much of the feedback to the now withdrawn proposal to raise the treadwear limit contained suggestions that the SEB better utilize the exclusion list, versus making a wholesale change to the treadwear limit. This proposal is in response to that feedback.

But then there was this:

The Solo Events Board has withdrawn the proposal published in the July Fastrack to put the Toyo Proxes R1R 195/50-15 tire on the exclusion for the Street Touring Category in 2013. The performance of this tire has generated a lot of controversy and kept the internet boards and forums humming. Despite some SEB members concerns about the performance of the tire, the overwhelming majority of member input supported keeping the tire as an option for Street Touring Classes. as a result, we will not put the 195/50-15 Toyo on the exclusion list for 2013.

This does not affect the recent rule change in Road Tire to raise the tread wear rating to 180.

All of this leaves me pretty well confused, but it definitely means that I'm waiting until the 2013 rules are officially published before I sink any cash into new tires.
