I just realized I posted this in the Classifieds on accident. My question is about if it is an open show and if so is there a tire rule or is it an open tire show. I think last year it was all four corners Hoosier. I don't see anything on the Brownstown website specifying any tire rules. Anybody know for sure if any tire rule this year?

I asked the track. They said USAC rules. But it is not sanctioned.

So hoosier on all four corners?

USAC's rule is a Medium on the RR only.
