Lots of interesting info here, and some stuff that I wasn't aware of, like the return of the BFG Rival.

Thank you GRM for putting this together!

Minor correction -- the picture for the Nitto is of an NT-05, not an NT-01.

I'm really excited to see what the new Continental/Hoosier collab tire does.

Thanks for this big test GRM! Now to go buy some more tires...

What is tread depth sensitivity? Tire performance in relation to wear?

Anybody know where to get the coopers beside extreme?  They don't have any in the 245 15 size in stock for the dry tire.

Tread block squirm... taller tread blocks are susecptible to moving or squirming and not having the responsiveness or wear that is most desirable.

I am running CR1 in 245/40/15 in autocross and so far I really like them!

Very fast and consistent!

Can we get a definitive answer to this question (if one exists)? Triangles on the sidewall. Wut?

Thanks!

Not officially a rollover indicator, though they do often tend to end up very close to the rubber seam (what you're actually aiming for most of the time, using all of the tread rubber without getting into the sidewall rubber) and are a decent reference point as a result.

Got it thanks. Makes me think of LT tires, muds especially

I'd like to see how the Firestone Firehawk Indy 500 compares to the Continental ECS and other tires in the non-200 TW summer performance class. I have a set on my street car and have been quite surprised at how well they grip, in both wet and dry conditions. 
 

If they were available in a 15 inch size, I would try them for an autocross rain tire on my Miata.

Nothing about the Federal Pros eh?

I think they are just fantastic budget 200tw tire.  I am really happy with them
