I tow livestock trailers and equipment trailers 80% of the time. Some loads are definitely more than my truck was rated to haul, but yet these tires and the truck just do the job and never give me any trouble. I have never had a tire last more than 36,000 miles. These are now at 44,000 and are completely smooth(worn out). I would highly recommend them. In 44,000 I never had a flat and that's a first. I travel gravel roads alot and they tend to eat other tires alive. Didn't seem to have any affect on the BFG's. It's hard to go wrong with this tire.
