I've had these size tires in M/T and an aggressive A/T up front for a couple winters. They are great for some things, not good for mileage unless you run them at higher PSI.
In order to get them to wear even decently even you need low pressures, I'm around 35psi front and 20 psi rear unloaded. And it still wears out the center faster than the shoulders. This hurts mileage but I love it for just about anything else. Rides so smooth and easy, and anything off-road or snow is just a blast. Unlike stock tires which cut through snow and leave you in trouble, these will float over and crawl through nearly anything. Same for soft dirt/sand.
Now I don't get to play in said conditions much...but it's fun nonetheless!
There is definitely a lot more side-wall play to get used to, but it's not crazy. It sure makes the garbage TTB front end behave a lot better with big soft tires.
Oh and they LOOK amazing!
