One of the improvements Toyo made from the AT2 to the AT3 was this!

I'll be very curious about their snow performance as well.
I've run BF Goodrich KO2s, Wrangler Duratracs on Rams in the snow.
Both were great, if you MADE me pick one, I liked the KO2 better, if for no other reason than personal biases.
I would trust both again.
I personally believe the 3PMSF rating is not to be dismissed, it's the real deal.
The tread and the rubber compound (at those low temperatures) have to work together to conquer that snow.
On a highway in a blizzard the duratracs were fantastic. I had incredible grip, and the highway wasn't well plowed.
The KO2s were used during a surprise snowstorm where no plows or salt made it to the road, and there were ice patches.
It was humbling for a lot of people. I think most drivers will say, "Oh I have AWD I'm fine." And they're riding on balding highway tires that "have enough tread." The tires were great in the snow!
On perfectly plowed and salted roadways. 2 years ago.
So many vehicles were stuck, or spinning, or sliding - the KO2s were perfect, I could have driven 40mph in 4x4 all the way home, and in some stretches I did, until the gridlock hit.
After that experience? There are a TON of tradeoffs I would make for absolute tire performance.
Cost, noise, a little MPG - I would give up all of those if needed to have F**king awesome traction in horrible conditions. At least where I live, on a snowy coast. I did not buy this factory offroader to be defeated by a little bit of rain or sleet!
