Honestly, I haven't got anything negative to say about the Toyo MT's in the snow.
I've only run this truck in powdery snow this past winter [dusting] so an honest review is absent and would be inaccurate. However, my previous truck - with the same tire/wheel setup as this one - did just fine in several snow conditions from powdery to about 8" we got here in VA a few winters back. No complaints and certainly no noticeable experiences that stuck.
Any more than that much snow and I wouldn't know
Truck was sold today [5/19]. I got an offer I couldn't turn down. I had no more need for a pickup so I cut it loose. About to purchase a '14 Jeep SRT8 this week.
