Cab...the classes like he's trying to run make you run a normal street tire. No type of drag tire is allowed.

I have used WD-40 in the past and it works. Buy it in a jug and roll it onto the tread surface w/ a paint roller. Let em sit overnight.
Makes them real sticky, but doesn't last but for a few passes.
