To be quite frank, the Carlisl;e turf master is the best front tire hands down, even over the sno-hogs, been there done that, for the rear there's two real good options carlisle turf masters for a soft or grass track and the tur-pro's for a hard pack dirt or clay, thats if ya running 8 dia. on the rear, Sno hogs work well where the dirt is garden soft or in sand on a hrd surface they can't get eny grip mainly because the lugs don't have enough surface contact area.
