I have these on my lifted 2002 Land Rover Discovery. Mostly driven off road and around town, but frequently up to 85ish mph and they're smooth as butter, quiet and even better, they grip the sandy soil around here like a champ. Sometimes I consider going to a full on M/T tire for off roading but these really do great, I've had them in deep water with a sandy bottom way over their 32 height an they've kept me moving just fine 95% of the time. In the one ice/slush storm we had here in October I couldnt get the truck to break loose or slide or anything (full time 4wd helps)... My dad has the Duratrac on his pickup and they do well also, but these are infinitely quieter and seem to grip mud and muck ALMOST as good. I would get them again in a heart beat.
