Depends on lots of factors, is it hi bite? Dry or moist? tight twisty or open layout?
Pretty much, ask around and see what the "fast guys" are running.
On a hi bite usually moist indoor clay track around here we usually run Losi Pink Tapers, Losi Red 8 Ribs, and rarely Losi Pink Directionals/Pro-Line Edges. That is when we are not running slicks all around!
