All our offroaders use Slicks or a variation, as Mark states, Primes have become very popular.
Foams are ONLY allowed in SC, no other class.
Its hard to judge a "fast tire" but as mark stated, the Schumi pins tend to dominate esp if its thicker or more commercial grade carpet or astro. With our Ozite and how much it cost, the track owner made a decision for slicks and that combined with traction compound (1 allowed compound sold at the store) it helps out not only the offroad, but onroad as well.

To clarify, one of our carpet OffRoad track in the area is slicks-only, the other allows pins and they do vastly outrun slicks there.
