I suppose the main reason I get such long life is having D rated tires and keeping a near perfect contact patch at 42-45 psi. I'm well aware that E rated would net me less than 75% of what I currently get in total tread life. I wouldn't be running these if I was going to tow alot. For that matter, if you run gravel any distance, BFG ATs are the wrong choice.
