I really wish super secret tires were not an option at worlds. It would be cool if they had some kind of spec tire. I bet most are running pinks...why not just spec it out.
They make such a big deal about the rubber tire rules and then the 1/12th scale rules for tires are so open.
I don't think we will ever know who is the best in the world until they put rules in place that will not allow some special compounds to determine the winner.
