Matt and I figured this out last night, and I just PM'd Dean about it...

Here's the gist of the above:

Because RE070's are OE tires on STI's, the STI's can run them. However, because they're not made in enough sizes, they cannot be used on anything other than the STI, which means all you WRX folks on RE070s are boned, even if you run in classes where R-compounds are legal!

One side question was regarding legal street tires for our regional ST modifier. According to our suplimental regulations, we define a street tire as "any tire with a treadwear rating of 140 or greater". Now, we might want to change that to "any nationally legal tire with a treadwear rating of 140 or greater" just to be clear, because I think it's implied you have to run a DOT and SCCA approved tire to begin with.

The bottom line is, RE070's are probably illegal on anything except the STI.

However, the good news is that I think the RT-615's are both faster and cheaper (aside from STI takeoffs that seem to turn up).

I got a meeting to run to, I'll explain a bit more when I get back if necessary.
