Anyone tow their 5'r with Cooper AT3's??

I'll post this since you have a GM. I ended up with a set of Coopers on my '11 Silverado Dually because I needed tires and my Tire Dealer couldn't get my usual Goodyears in time for a trip. Saved me a few bucks and told me they were a good tire. Which they were until they got approx 10K miles on them, then when ever in a sweeping curve at highway speed I would get vibration in the front that could be felt in the steering wheel and you could feel the uneven wear on the outer edges of the front tires. Moved them to the back and everything was fine for another 10 or 15K miles then it started all over again, this happened running Solo or towing heavy. Finally pulled them off and put on the Goodyear Wranglers with the Kevlar belts and no more vibrations until they were due for replacement.
For what ever reason those Coopers didn't like my stock front suspension, so no more Coopers for me.
