That is a problem Chris. It was already announced here by a board member that we could use the new tires. I've got a set mounted already to go... Further it has been said all year we were going to switch, I think it's the end of the season for us, and we should be able to test some things under race conditions for next year.
I think its worse since the club previously said we could use them, and it was given the OK in the thread below by an officer over a week ago
