Well, after hunting the truck with the Duratracs for two weeks in really bad conditons, I can tell you they are a huge improvement over the Firestone ATs I just had taken off after 3000 miles. I have used Duratracs on my off road rigs for decades, and tried many other tires. some work better off road, some work better on road, but I have not found one that I like better for dual duty and year round use where I don't have to change tires summer and winter.
I have never seen the blowout issues, flats etc, though I have seen the odd one that needed to be replaced because it took too much weight to balance. I have never had a dealer install a tire that took too much weight, they replaced it right away during the initial install. All large E type truck tires will occasionally have a tire that is out of normal weight distribution, if you have tire dealers that put defective tires on your truck you need a new dealer.
