Top part of picture taken on a Saturday; bottom part taken the next day after a PCA-SDR autocross.
Multiple tears in the rubber on the shoulder; the outermost of the center ribs is peeling away badly.
These tires were five months old, and I didn't autocross on them again. When I took the tire into a tire shop shortly after this to have a puncture repaired, they told me all they could do was plug it without dismounting it -- due to the tears in the shoulder, they didn't feel they could safely dismount and remount the tire.
If we claim to be "safety first", we should at least let SS competitors have their pick of tires that are safe for autocross, and that stay safe for at least multiple events.

For what it's worth, no, that was the driver's side rear tire.

Or can it be a place where serious competitors can compete against other serious competitors in cars that are very close to equal in performance?

This describes the CC classes, not SS, right?

I'm not suggesting that every car that ends up classed in SS06 will be equal in performance -- however, I'm suggesting that everybody who optimizes an SS06 car is probably going to end up at a very similar place, no matter where they plan to run. You can't say that about the CC classes, where optimizing for a big track is very different than optimizing for autocross.

More drivers in SCCA do this and they typically know which cars are the best to use in each street class., Most of our SS drivers tend to be new drivers who've come out to play with their car and see what it can do. It's a different competitive culture.
