^ Toyo AT and Nitto Terragrapplers are both excellent choices with the Nitto being a better price point and the Toyos being a bit quieter.

Regarding snow traction, both are quite good and Cascade Concrete is about the worst possible combination of barely frozen water and high overall moisture content.

Worth noting, as good an all around tire as the Toyo AT is, for wet and snow traction, siped Toyo ATs are literally on par with dedicated snow tires with better overall treadwear.

That said, if primarily hauling heavy (TC, heavy pin weight etc), that condition will cause quicker treadwear if siped, whereas moderate weights (like a TT) will not.
Barring other factors like driving style and surface/geographical conditions.
In general, aftermarket siping does not appreciably reduce tire tread life in my experience, despite the logical thought that it will.
Just food for thought.
It’s one of those old school “tricks” that really does work and with zero risk.
