My experience with the Toyo AT2's on my 2015 1500 were just fine. Not the best winter tire, but I just slowed down and went right through all kinds of stuff anyway. The AT3s are supposed to be slightly better. Toyo rates them at 4 out of 5 vs 3.5 for the AT2s It's got 40,000 miles and the tires still have a LOT of tread. My 2018 2500 has the newer Nittos. Less road noise than the Toyos on the 1500. Nitto handling on roads is pretty similar in most conditions, but better in the snow. That could be because the truck is heavier than the 1500, but other people have noted similar experiences. The Nittos are a lot better on wet roads. The Toyos slip quite easily. The Nittos just look so much better than the Toyos, even the newer AT3s.
I've driven northern and central Illinois for decades. We get plenty of snow here, but we don't end up with all that much snow most of the time. In really bad storms, you might see a few days of snow on country roads, but everything else is usually cleared within a day after the snow. While snow sits on the ground most of the winter, total road snow driving might be 10 to 20 days out of the year. Maybe more in a really rough year. I just don't see enough here to worry too much about winter tires if I've got good all-season tires. I've driven through 4" and more of virgin snow in both tires without problems. Reduce speed when warranted, and use 4WD judiciously.
I don't envy those of you living further north.
