I've had two sets of those junkers, both on new Rams. Look at Tire Rack ratings if you don't believe me. They are so bad, to me they are dangerous on wet roads. I got rid of mine immediately.
I started this thread for non-AT tires. I see you are in the same predicament. To date, at least according to Tire Rack Survey, the top three HT for HD trucks are Michelin Defenders, Continental HT, and Goodyear Workhorse HT.
I keep hearing Michelin problems with balance and delamination across the board, even to motorcycles.
@Burla has posted some information related to issues with using recycled materials.
Posters on this site have noted recent problems with Cooper as well. I had Continental long ago that separated.
I have been running General Grabber ATX, and they have been excellent, everything reviewers noted they do. But their HT is not rated highly. General is owned by Continental now, btw.
Goodyear has historically made a good medium duty truck tire. Those on my RV were excellent, but their consumer tires have never been good.
