this site under off road tires gives good info, after that it comes down to preference.

Proline bow ties where my latest purchase unfortunatley i only put a couple of laps down with them on a dusty hard packed track before the heavens opened and i went home, they felt better then the crimefighter i've just about always used but they where the m3 compound. crimefighter have always been abit "edgy" thats why most trim the outside tread of them to "calm" them down abit.
