Chevrolet Performance LSX Challenge Series and LSX Shootout - Tire rules for the LSX truck class.

What are the tire limitations for the LSX truck class? Can a full drag slick be ran? Does it have to be a DOT approved tire, radial, etc? I have been looking through the rules and don't see anything mentioned. Thanks.

we ran slicks last year when it was one class so I don't see why it would be different now that we are two classes.
