I am really liking my new Falken's. Haven't had a set Coopers since my 1998 Ranger, but had issues with those and the local Cooper dealer, so I will not go that route any longer. Last set on my 2012 F150 was BFG KO2's. They were good other than sucked on wet roads.
Just installed the Cooper AT3 XLT's on my 21 (275 65 20). I chose them for several reasons one being the weight. They were on the lower range of tires I was considering. So far I am very happy. They balanced well (I'm picky), very quiet, and are 3 peak rated. Time will tell if it was a good choice. I ran Falkens on my wife's 2018 Wrangler and they were great as well. I thought they were noisier than the Coopers but not by much. In my size, the Coopers are 60lbs and Falkens are 66lbs. Not a huge difference.
I just completed a 450 mile round trip in northern Minnesota. The first day was mid 30's and rain the entire day. The return trip home was snow covered, slush and ice the entire trip.
The Wildpeaks did not disappoint at all. And quiet the whole time as well.
I had p275/60/20 on factory wheels for over 45k miles with no issues. I bent a wheel and purchased 18s with 275/65/18 wildpeaks as well. No complaints and i like them a lot more than BFGs. They are my go to, as long as they my size.
