I ran the transforce AT after the stock continentals ran out. I switched to the transforce HT and am now on my second set of those on my f350. I got a bit over 50k and probably could have gone to 60. I am now at 10k on transforce ht on this set and really like them. They are quiet and do fine in our snow here, in the desert near Reno. I live approx 5 miles down a dirt road. Only chained them once when hunting. My heaviest trailer is 7500# but I like the way they wear evenly and don't get lumpy. They cost 167 ea here so the price is right for the wear and handling.
