I use these tires mostly for work duty with my F150. Sales guy convinced me to get the heavier ply due to all the trailer pulling I do (40% of the miles). I drive everything from highway to back roads and plenty of offroad as well. (Seismic lines, farm fields, frozen ATV trails, etc). Tires have been quite impressive up until for the first 25 thousand miles or so. After that, the really soft grippy compound is worn and the tire is more like and all season with more ice snipes. Tires have been very tough, no flats even though I regularly pull sticks and branches out of my frame, bumpers, grill, etc. They are definitely a heavier tire and take a little more steering and power to move but well worth the trade off for heavy duty use. I will likely get at least 50k miles out of the set but if extreme winter performance is required I would have replaced around 30k miles.
So in summary, great HD tire, good wear, bit heavy. Worth the money IMO.
