My 3rd year running them all season and been extremely happy with traction and wear!! We get some nasty winters and zero issues with snow. Ice is the biggest weakness so far.

These tires were one of the best I have run on my last 3 F250 6.2L trucks (2017, 2019 & 2022). Very well rounded performance.
I work in the oil field, with lots of stop and go on gravel. I drive lots of mud, deep deep snow, gravel and a light mix of highways in Canada.
I was very pleased with the winter performance, these tires grip very well in snow and mud. They do lack on ice grip but this is a sacrifice I'm willing to make.
The whisper grooves keep the tire noise tamed but not entirely muted. They do have a slight constant noise but this does not bother me.
I found the tires to be exceptionally durable, not chipping away and destroying the tires as I drove them on lots of gravel. This is a common problem we face in the oilfield.
I would recommend these tires if your interests align with mine in this order:
1: Mud and Snow performance - EXCELLENT!
2: Tread life - EXCELLENT! They hold up to chipping from stones very well.
3: Cost - Affordable, $1850 CAD installed and balanced when I got them.
4: Ice - Drive accordingly to the road conditions - This is my least important factor. These tires are not disappointing on ice but they definitely lack here.

I drive about 50% highway and 50% gravel using my truck to check wells. Meaning I stop and go every few 100 meters on gravel and we chew tires up faster then the normal person.
These tires inspired confidence in snow and mud, they fall short on ice as expected but this is not a huge concern to me. The seemed to pack snow into the tread that held the snow on snow traction i require at work.
Since my work pays for tires this allows me to try a new tire any time i need new shoes. And these were the best tread life i have ever had. The tires had over 70000km of abuse on them under my F250. I usually only get 40000-55000km per set. Putting these well above the pack

Other tires ive used include:
Mickey tompson baja atz - lasted 40000km before having dangerous delamination on 2 tires. Loved these tires up to that point.
Toyo at2 extremes - ran 2 sets. Both averaged around 50000km. Durable casing. Great tires.
Toyo at3 - these tires are much softer then at2 and didnt last as long. Roughly 40000km. Overall a good tire, just expensive.
Hankook dynapro at2 -lasted 60000km. I didnt enjoy these tires, they are terrible in snow and mud. Good on icy highways. For my use case i wouldnt get them again.
